Example Question #41 : How To Add

Destiney borrowed $25 from Peter, $15 from Blair, and $9 from Scarlet. How much money did Destiney borrow in all?

Possible Answers:

\(\displaystyle \$ 64\)

\(\displaystyle \$ 49\)

\(\displaystyle \$ 59\)

\(\displaystyle \$ 26\)

\(\displaystyle \$ 45\)

Correct answer:

\(\displaystyle \$ 49\)

Explanation:

Since Destiney is gaining money over time (due to her borrowing money from other people), we should add the three numbers together to find out how much money Destiney borrowed in all!

\(\displaystyle \$ 25 + \$ 15 + \$ 9 = \$ 49\)

Example Question #2 : Adding Multi Digit Decimals

\(\displaystyle 33.4 + 22.7 =\)

Possible Answers:

\(\displaystyle 16.3\)

\(\displaystyle 56.1\)

\(\displaystyle 121.2\)

\(\displaystyle 10.7\)

\(\displaystyle 34.8\)

Correct answer:

\(\displaystyle 56.1\)

Explanation:

Add the "whole" parts of the numbers:  \(\displaystyle 33 + 22 = 55\)

Add the "decimal" parts of the numbers: \(\displaystyle 0.4 + 0.7 = 1.1\)

Add both parts together: \(\displaystyle 55 + 1.1 = 56.1\)

 

 

\(\displaystyle 33.4 + 22.7 = 56.1\)

Example Question #42 : How To Add

The Oglevee Family Farm has 12 chickens, 4 pigs, 18 horses, and 2 cows. How many animals does the Oglevee Family Farm have in all?

Possible Answers:

\(\displaystyle 44\)

\(\displaystyle 28\)

\(\displaystyle 36\)

\(\displaystyle 101\)

\(\displaystyle 48\)

Correct answer:

\(\displaystyle 36\)

Explanation:

Since we need to figure out the total number of animals at the Oglevee Family Farm, we need to add the number of chickens, pigs, horses, and cows together.

\(\displaystyle 12 + 4 + 18 + 2 = 36\)

Example Question #888 : Operations

Arlie is buying Hanukkah gifts for his family. He buys a \(\displaystyle \$24\) scarf for his mother, a \(\displaystyle \$18\) basketball for his brother, and a \(\displaystyle \$33\) tie for his father. How much total money does Arlie spend?

\(\displaystyle \$75\)

\(\displaystyle \$85\)

\(\displaystyle \$101\)

\(\displaystyle \$56\)

Correct answer:

\(\displaystyle \$75\)

Explanation:

We need to add the cost of the three gifts together to find how much money Arlie spent in all.

\(\displaystyle \$24 + \$18 + \$33 = \$75\)

Example Question #43 : How To Add

Calculate the sum:

\(\displaystyle 72+53\)

Possible Answers:

\(\displaystyle 115\)

\(\displaystyle 98\)

\(\displaystyle 152\)

\(\displaystyle 125\)

\(\displaystyle 135\)

Correct answer:

\(\displaystyle 125\)

Explanation:

Add the ones column first \(\displaystyle \left (2+3\right )\) then add the tens column \(\displaystyle \left ( 7+5\right )\).  The sum is 125.

Line up the two numbers and add vertically, starting with the ones place.

      \(\displaystyle 230\)

\(\displaystyle \underline{+\352}\)

     \(\displaystyle 582\)

\(\displaystyle 135\)

\(\displaystyle 3500\)

\(\displaystyle 875\)

\(\displaystyle 450\)

Correct answer:

Explanation:

\(\displaystyle \fn_cm Line\;up\;the\;numbers\;and\;add\;straight\;down.\)

 \(\displaystyle 100\)

\(\displaystyle \underline{+35}\)

  \(\displaystyle 135\)

Example Question #46 : How To Add

\(\displaystyle 435+99=\)

\(\displaystyle 504\)

\(\displaystyle 434\)

\(\displaystyle 422\)

\(\displaystyle 522\)

\(\displaystyle 534\)

Correct answer:

\(\displaystyle 534\)

Explanation:

\(\displaystyle Line\;up\;the\;numbers\;and\;add\;straight\;down.\)

  \(\displaystyle \fn_cm \not{4}^{5}\not{3}^{4}\;5\)

  \(\displaystyle \fn_cm \fn_cm \fn_cm \fn_cm \underline{+\;\;\;9\;\;\, 9}\)

     \(\displaystyle 5\;\;3\;\;4\)

 

\(\displaystyle \fn_cm 5\;+9=\underline{1}4\)

\(\displaystyle \fn_cm \fn_cm \fn_cm \fn_cm Carry\;the\;1.\;Add\;the\;1\;to\;the\;3\;in\;4\underline{3}5.\)

\(\displaystyle \fn_cm 4+9=\underline{1}3\)

\(\displaystyle Carry\;the\;1.\;Add\;the\;1\;to\;the\;4\;in\;\underline{4}35.\)

\(\displaystyle 5+0=5\)

\(\displaystyle Answer:\;534\)

 

 

 

Example Question #47 : How To Add

What is \(\displaystyle \frac{1}{2} + \frac{1}{4}\)?

Possible Answers:

\(\displaystyle \frac{3}{2}\)

\(\displaystyle \frac{2}{6}\)

\(\displaystyle \frac{3}{4}\)

\(\displaystyle \frac{2}{4}\)

\(\displaystyle \frac{1}{6}\)

Correct answer:

\(\displaystyle \frac{3}{4}\)

Explanation:

To add fractions, first find a common denominator, which in this case is 4. To turn \(\displaystyle \frac{1}{2}\) into a fraction with 4 as a denominator, multiply the numerator and denominator by 2.

Then add \(\displaystyle \frac{2}{4}\) and \(\displaystyle \frac{1}{4}\) to get \(\displaystyle \frac{3}{4}\).

Example Question #48 : How To Add

Mr. Johnson is buying Christmas presents for his family. He spends \(\displaystyle \$45\) on perfume for his wife, \(\displaystyle \$18\) on a sweatshirt for his daughter, and \(\displaystyle \$11\) on a baseball glove for his son. How much money does Mr. Johnson spend in all?

\(\displaystyle \$100\)

\(\displaystyle \$84\)

\(\displaystyle \$78\)

\(\displaystyle \$74\)

Correct answer:

\(\displaystyle \$74\)

Explanation:

To find the total amount of money that Mr. Johnson spent on Christmas gifts, we need to add the individual price of each gift together.

\(\displaystyle \$45 + \$18 + \$11 = \$74\)
