Question 1

Which list shows ONLY fractions that are equal to whole numbers?

  1. 21, 44, 62\frac{2}{1},\ \frac{4}{4},\ \frac{6}{2} (correct answer)
  2. 31, 23, 66\frac{3}{1},\ \frac{2}{3},\ \frac{6}{6}
  3. 55, 42, 34\frac{5}{5},\ \frac{4}{2},\ \frac{3}{4}
  4. 12, 22, 41\frac{1}{2},\ \frac{2}{2},\ \frac{4}{1}
Explanation: A fraction equals a whole number when the numerator can be divided evenly by the denominator with no leftover pieces. Think of a fraction as division: ab\frac{a}{b} means a÷ba \div b. If that division gives you a whole number (no remainder), the fraction equals a whole number. Look at choice A: 21=2\frac{2}{1} = 2, 44=1\frac{4}{4} = 1, and 62=3\frac{6}{2} = 3. Every fraction in this list divides evenly into a whole number, so A is correct. Choice B fails because of 23\frac{2}{3} — since 2 cannot be divided evenly by 3, this fraction is less than 1 and not a whole number. Choice C fails because 34\frac{3}{4} is less than 1 (3 cannot be split evenly into 4 equal wholes). Choice D fails because 12\frac{1}{2} is only half of a whole, not a whole number. A helpful pattern to remember: a fraction equals a whole number in two common situations — when the denominator is 1 (like 41=4\frac{4}{1} = 4), or when the numerator and denominator are the same (like 55=1\frac{5}{5} = 1), or when the numerator is a multiple of the denominator (like 62=3\frac{6}{2} = 3). If the numerator is smaller than the denominator, the fraction is less than 1 and cannot be a whole number. Scan each list for that trap first — one "small over big" fraction knocks out the whole choice.

Question 2

Eight one-fourth pieces make 2 wholes. Which fraction equals 2?

  1. 12\frac{1}{2}
  2. 84\frac{8}{4} (correct answer)
  3. 48\frac{4}{8}
  4. 24\frac{2}{4}
Explanation: Eight pieces, each equal to one-fourth, make 8/4, which equals 2 wholes, so Choice B is correct. Choice A (1/2) and Choice D (2/4) are both less than 1. Choice C (4/8) equals 1/2, which also does not equal 2.

Question 3

Ana is making a pattern with fractions that equal whole numbers. She starts with 44\frac{4}{4}, then 84\frac{8}{4}, then 124\frac{12}{4}. If she continues this pattern, what whole number will her next fraction equal?

  1. 44 (correct answer)
  2. 33
  3. 55
  4. 1616
Explanation: When you see fractions in a pattern, look for what's changing in both the numerator (top number) and denominator (bottom number). Here, Ana's pattern shows numerators of 4, 8, and 12, while the denominator stays 4. The numerators are increasing by 4 each time: 4 + 4 = 8, then 8 + 4 = 12. Following this pattern, the next numerator should be 12 + 4 = 16, giving us 164\frac{16}{4}. Now you need to convert this fraction to a whole number by dividing: 16 ÷ 4 = 4. Let's check why each answer choice works or doesn't work. Choice A (4) is correct because 164=4\frac{16}{4} = 4. Choice B (3) would mean the fraction equals 3, but 124=3\frac{12}{4} = 3 was already the previous term in the sequence. Choice C (5) doesn't fit the pattern—there's no fraction with denominator 4 in this sequence that equals 5. Choice D (16) is the numerator of the next fraction, not the whole number it equals. This is a common mistake when students confuse the fraction itself with its simplified value. Remember that when working with fraction patterns, always check both what the pattern is doing and what the question is asking for. Here, the pattern was in the numerators, but the question asked for the whole number value, not the fraction itself.

Question 4

Which fraction is equal to the whole number 55?

  1. 15\frac{1}{5}
  2. 51\frac{5}{1} (correct answer)
  3. 55\frac{5}{5}
  4. 105\frac{10}{5}
Explanation: When you see a fraction, remember what it really means: the top number (numerator) is how many parts you have, and the bottom number (denominator) is how many equal parts make one whole. A quick way to turn a fraction into a number is to divide the top by the bottom. To find which fraction equals 55, look for one where top ÷\div bottom =5= 5. That's 51\frac{5}{1}, because 5÷1=55 \div 1 = 5. Think of it this way: if a whole is cut into just 11 piece (meaning it isn't cut at all), then 55 of those "pieces" is just 55 whole things — answer B. Choice A, 15\frac{1}{5}, means 11 out of 55 equal parts — that's a small piece, much less than 11, not 55. Choice C, 55\frac{5}{5}, means you have all 55 out of 55 parts, which equals exactly 11 whole, not 55. Choice D, 105\frac{10}{5}, equals 10÷5=210 \div 5 = 2, which is a whole number but not the right one. Study tip: any whole number can be written as a fraction by putting it over 11. So 3=313 = \frac{3}{1}, 7=717 = \frac{7}{1}, and so on. Also remember that any fraction with the same top and bottom (like 55\frac{5}{5} or 88\frac{8}{8}) always equals 11. These two patterns show up often on 3rd-grade fraction questions!

Question 5

Which statement is TRUE?

  1. 22\frac{2}{2} is greater than 11.
  2. 71\frac{7}{1} is equal to 77. (correct answer)
  3. 17\frac{1}{7} is equal to 77.
  4. 77\frac{7}{7} is equal to 77.
Explanation: Fractions are really just division problems in disguise. The fraction bar means "divide," so ab\frac{a}{b} is the same as a÷ba \div b. Keeping this in mind helps you handle special cases like fractions with 11 in the denominator or fractions where the top and bottom are equal. Look at choice B: 71\frac{7}{1} means 7÷17 \div 1. Dividing any number by 11 gives you that same number back, so 71=7\frac{7}{1} = 7. That makes B true. Choice A claims 22\frac{2}{2} is greater than 11, but when the numerator and denominator are the same, you have one whole. 22=1\frac{2}{2} = 1 exactly — not greater than 11. Choice C says 17\frac{1}{7} equals 77, but 17\frac{1}{7} means you split one whole into 77 equal pieces and take just one piece. That's a tiny amount, much less than 11, definitely not 77. Choice D says 77\frac{7}{7} equals 77, but again, when top and bottom match, the fraction equals 11. Seven parts out of seven equal parts is one whole pizza, not seven pizzas. A helpful pattern to memorize: n1=n\frac{n}{1} = n (denominator of 11 leaves the number unchanged), and nn=1\frac{n}{n} = 1 (same top and bottom always equals one whole). Mixing these two rules up is one of the most common fraction traps — practice spotting the difference quickly.

Question 6

Jaden has 44 whole granola bars. He wants to write the total number of bars as a fraction with a denominator of 11. Which fraction should he write?

  1. 14\frac{1}{4}
  2. 41\frac{4}{1} (correct answer)
  3. 44\frac{4}{4}
  4. 82\frac{8}{2}
Explanation: Any whole number can be written as a fraction by placing it over 11. That's because a denominator of 11 means the whole is divided into just one piece — itself — so the fraction equals the numerator. For example, 51=5\frac{5}{1} = 5 and 101=10\frac{10}{1} = 10. Since Jaden has 44 whole granola bars, you write 44 as the numerator and 11 as the denominator, giving 41\frac{4}{1}. That matches choice B. Choice A, 14\frac{1}{4}, flips the numbers. This fraction means one out of four equal parts of a single bar — much less than one whole bar, not four whole bars. Choice C, 44\frac{4}{4}, equals just 11 whole (four out of four equal parts make one complete bar), not four. Also, its denominator is 44, not 11, so it doesn't fit the requirement. Choice D, 82\frac{8}{2}, does equal 44, but its denominator is 22, not 11, so it doesn't match what the question asked for. A helpful tip: when a problem asks you to write a whole number as a fraction with a denominator of 11, just place the whole number on top of 11. And always double-check that your fraction meets both conditions in the question — the right value and the right denominator.

Question 7

Mrs. Chen asks her students to find three different fractions that all equal 33. Tommy writes 31\frac{3}{1}, 62\frac{6}{2}, and 93\frac{9}{3}. Sarah writes 124\frac{12}{4}, 155\frac{15}{5}, and 186\frac{18}{6}. Who wrote three correct fractions?

  1. Only Tommy wrote three correct fractions
  2. Only Sarah wrote three correct fractions
  3. Both Tommy and Sarah wrote three correct fractions (correct answer)
  4. Neither Tommy nor Sarah wrote three correct fractions
Explanation: Tommy's fractions: 31=3\frac{3}{1} = 3, 62=3\frac{6}{2} = 3, 93=3\frac{9}{3} = 3. All equal 3. Sarah's fractions: 124=3\frac{12}{4} = 3, 155=3\frac{15}{5} = 3, 186=3\frac{18}{6} = 3. All equal 3. Both students wrote three correct fractions that equal the whole number 3.

Question 8

The number line shows a point labeled PP located at the same place as the whole number 11. Which fraction could be the label for point PP?

  1. 14\frac{1}{4}
  2. 24\frac{2}{4}
  3. 44\frac{4}{4} (correct answer)
  4. 41\frac{4}{1}
Explanation: 44\frac{4}{4} means all 4 of the 4 equal parts, which equals 1 whole. 14\frac{1}{4} and 24\frac{2}{4} are less than 1. 41\frac{4}{1} equals 4, not 1.

Question 9

Refer to the number line. Which whole number is at the same point as 82\frac{8}{2}?

  1. 22
  2. 33
  3. 44 (correct answer)
  4. 88
Explanation: 82\frac{8}{2} means 8 halves. Since 2 halves make 1 whole, 8 halves make 4 wholes. So 82=4\frac{8}{2}=4.

Question 10

The diagram shows 33 same-sized rectangles. Each rectangle is divided into 44 equal parts, and every part is shaded. Which fraction represents the total shaded amount?

  1. 34\frac{3}{4}
  2. 44\frac{4}{4}
  3. 124\frac{12}{4} (correct answer)
  4. 1212\frac{12}{12}
Explanation: Each rectangle has 4 fourths shaded. Three whole rectangles have 4+4+4=124+4+4=12 fourths shaded, which is 124=3\frac{12}{4}=3. Choice A is only three parts of one rectangle. Choice B is only one whole. Choice D equals 1 whole.

Question 11

Ben says: 'If I have 22 whole apples and I write it as a fraction of halves, I get 22\frac{2}{2}.' What mistake did Ben make?

  1. He should have written 42\frac{4}{2}, because 22 wholes have 44 halves. (correct answer)
  2. He should have written 24\frac{2}{4}, because there are 44 halves in 22.
  3. He is correct; 22\frac{2}{2} equals 22.
  4. He should have written 12\frac{1}{2}, because each apple is a half.
Explanation: When you're converting whole numbers into fractions, the key idea is to ask: "How many of these fractional pieces fit inside my whole?" If you're using halves, you need to count how many half-pieces make up each whole apple. Picture 22 whole apples. If you cut each apple into halves, each apple gives you 22 halves. So 22 apples ×2\times 2 halves each =4= 4 halves total. Written as a fraction, that's 42\frac{4}{2}, which confirms answer A. The denominator (22) tells you the size of each piece (halves), and the numerator (44) tells you how many of those pieces you have. Choice B flips the fraction to 24\frac{2}{4}, which actually means "22 out of 44 equal parts," or one-half of a single apple — much less than 22 whole apples. Choice C claims Ben is correct, but 22\frac{2}{2} equals just 11 whole apple, not 22. Ben only counted the wholes in the numerator and forgot to convert them into halves. Choice D gives 12\frac{1}{2}, which is only half of one apple — Ben would be throwing away almost all his fruit! A helpful trick: when turning a whole number into a fraction with a specific denominator, multiply the whole number by the denominator to get the numerator. For 22 wholes in halves: 2×2=42 \times 2 = 4, so 42\frac{4}{2}. This pattern works for any conversion — 33 wholes in fourths would be 124\frac{12}{4}.

Question 12

Which pair of numbers are located at the SAME point on a number line?

  1. 33\frac{3}{3} and 33
  2. 36\frac{3}{6} and 33
  3. 13\frac{1}{3} and 33
  4. 31\frac{3}{1} and 33 (correct answer)
Explanation: When you see a fraction, remember what it really means: the top number (numerator) is how many pieces you have, and the bottom number (denominator) is how many equal pieces make one whole. A fraction like ab\frac{a}{b} also means "a divided by b." That's the key to comparing fractions with whole numbers on a number line. To land on the same point as 33, you need a fraction that equals 33. Look at choice D: 31\frac{3}{1} means 3 divided by 1, which equals 33. So 31\frac{3}{1} and 33 sit on the exact same spot on the number line. ✓ Choice A, 33\frac{3}{3}, means 3 divided by 3, which equals 11 — not 3. That fraction lands on 11, not 33. Choice B, 36\frac{3}{6}, is only half of one whole (0.50.5), nowhere near 33. Choice C, 13\frac{1}{3}, is just one piece out of three equal pieces of a whole — a tiny amount between 00 and 11, definitely not 33. Tip: When a fraction has 11 as the denominator, the fraction equals the numerator (51=5\frac{5}{1}=5, 71=7\frac{7}{1}=7). And when the numerator and denominator are the same, the fraction equals 11 (44=1\frac{4}{4}=1). Memorizing these two patterns will help you quickly match fractions to whole numbers on a number line.

Question 13

Which fraction is equal to the whole number 3?

  1. 31\frac{3}{1} (correct answer)
  2. 33\frac{3}{3}
  3. 13\frac{1}{3}
  4. 32\frac{3}{2}
Explanation: Any whole number can be written as a fraction with a denominator of 1, so 3 = 3/1, making Choice A correct. Choice B, 3/3, equals 1, not 3. Choice C, 1/3, is less than 1. Choice D, 3/2, equals 1 and a half, not 3.

Question 14

On the number line, 3 is at the same point as which fraction?

  1. 31\frac{3}{1} (correct answer)
  2. 13\frac{1}{3}
  3. 33\frac{3}{3}
  4. 32\frac{3}{2}
Explanation: This question tests expressing whole numbers as fractions and recognizing fractions that equal whole numbers (CCSS.3.NF.3.c), specifically understanding that n = n/1 and that fractions like 4/4 equal 1. Any whole number can be written as a fraction by putting it over 1. For example, 3 = 3/1 (three ones). Also, when a fraction has the same numerator and denominator (like 4/4, 6/6), all parts are shaded and it equals 1 whole. Multiple wholes work too: 8/4 means eight fourths, which is 2 wholes (because 4 fourths make 1 whole, so 8 fourths make 2 wholes). The number line shows the whole number 3 and equivalent fractions at the same point, demonstrating equivalence like 3 and 3/1 at the same location. Choice A is correct because 3/1 equals 3, showing understanding that whole numbers can be expressed as fractions and vice versa. Choice B is incorrect because 1/3 equals about 0.333, not 3; this error occurs when students reverse numerator and denominator. To help students understand whole numbers as fractions: Use number lines showing whole numbers and fractions at same point (1 and 2/2, 3 and 6/2). Show physical models: one whole circle = 2/2 = 3/3 = 4/4 (all parts shaded). Teach pattern: any whole number n = n/1 ("n ones"). Emphasize 4/4 = 1, 8/4 = 2 by counting fourths. Practice locating equivalent wholes and fractions on number lines. Watch for students who reverse numerator/denominator or don't recognize full fractions equal wholes.

Question 15

Use the table to answer the question. Which student correctly wrote the whole number as a fraction?

  1. Emma correctly wrote her whole number as a fraction
  2. Liam correctly wrote his whole number as a fraction (correct answer)
  3. Both Emma and Liam correctly wrote their fractions
  4. Neither Emma nor Liam correctly wrote their fractions
Explanation: Emma wrote 5 as 55=1\frac{5}{5} = 1, which is incorrect since 55=1≠5\frac{5}{5} = 1 \neq 5. Liam wrote 3 as 93=3\frac{9}{3} = 3, which is correct since 93=3\frac{9}{3} = 3. Only Liam correctly expressed his whole number as a fraction.

Question 16

Look at the number line. Point AA is located at the same position as which fraction?

  1. 23\frac{2}{3}
  2. 66\frac{6}{6} (correct answer)
  3. 32\frac{3}{2}
  4. 16\frac{1}{6}
Explanation: Point A is located at 1 on the number line. The fraction 66=1\frac{6}{6} = 1, so it's at the same position as point A. Choice A equals 23\frac{2}{3} which is less than 1. Choice C equals 1121\frac{1}{2} which is greater than 1. Choice D equals 16\frac{1}{6} which is much less than 1.

Question 17

Which fraction is equivalent to the whole number 2?

  1. 13\frac{1}{3}
  2. 12\frac{1}{2}
  3. 21\frac{2}{1} (correct answer)
  4. 22\frac{2}{2}
Explanation: Two divided by 1 equals 2, so 2/1 is equivalent to the whole number 2. Choice A represents one part out of three, not the whole number 2. Choice B represents one half, not 2. Choice D equals 1, since 2 divided by 2 is 1, not 2.

Question 18

A number line from 0 to 1 is divided into 4 equal parts. Which fraction names the point at 1?

  1. 34\frac{3}{4}
  2. 41\frac{4}{1}
  3. 14\frac{1}{4}
  4. 44\frac{4}{4} (correct answer)
Explanation: Dividing the number line from 0 to 1 into 4 equal parts means each part is 1/4. The point at 1 is reached after all 4 parts, or 4/4, so D is correct. Choice A (3/4) is three of the four parts, not the whole. Choice B (4/1) reverses the numerator and denominator. Choice C (1/4) is only one of the four parts.

Question 19

Which fraction is equivalent to the whole number 1?

  1. 21\frac{2}{1}
  2. 13\frac{1}{3}
  3. 12\frac{1}{2}
  4. 22\frac{2}{2} (correct answer)
Explanation: The fraction 2/2 means 2 equal parts out of 2 total parts, which is the same as one whole, so D is correct. Choice A (2/1) equals 2, not 1. Choice B (1/3) is less than 1. Choice C (1/2) is also less than 1.

Question 20

A number line from 0 to 4 is divided into thirds, as shown. Which point on the number line shows the value of 93\frac{9}{3}?

  1. The point at 11
  2. The point at 22
  3. The point at 33 (correct answer)
  4. The point at 99
Explanation: 93=3\frac{9}{3}=3, since 3 thirds make each whole and 9 thirds make 3 wholes. Choice A would match 33\frac{3}{3}. Choice B would match 63\frac{6}{3}. Choice D confuses the numerator with the value.
