Example Question #494 : Common Core Math: Grade 4

Select the symbol to correctly fill in the blank below. 

\(\displaystyle \frac{3}{6}\) __________\(\displaystyle \frac{7}{14}\)

Possible Answers:

\(\displaystyle < \)

\(\displaystyle =\)

\(\displaystyle >\)

Correct answer:

\(\displaystyle =\)

Explanation:

To compare fractions, we need to first make common denominators. 

\(\displaystyle \frac{3}{6}\times\frac{14}{14}=\frac{42}{84}\)

\(\displaystyle \frac{7}{14}\times\frac{6}{6}=\frac{42}{84}\)

 

Now that we have common denominators, we can compare numerators. The fraction with the bigger numerator has the greater value. 

\(\displaystyle \frac{42}{84}=\frac{42}{84}\)

Example Question #41 : Extend Understanding Of Fraction Equivalence And Ordering

Select the symbol to correctly fill in the blank below. 

\(\displaystyle \frac{5}{10}\) __________\(\displaystyle \frac{1}{8}\)

Possible Answers:

\(\displaystyle < \)

\(\displaystyle =\)

\(\displaystyle >\)

Correct answer:

\(\displaystyle >\)

Explanation:

To compare fractions, we need to first make common denominators. 

\(\displaystyle \frac{5}{10}\times\frac{8}{8}=\frac{40}{80}\)

\(\displaystyle \frac{1}{8}\times\frac{10}{10}=\frac{10}{80}\)

Now that we have common denominators, we can compare numerators. The fraction with the bigger numerator has the greater value. 

\(\displaystyle \frac{40}{80}>\frac{10}{80}\)

Example Question #42 : Extend Understanding Of Fraction Equivalence And Ordering

Select the symbol to correctly fill in the blank below. 

\(\displaystyle \frac{4}{6}\) __________\(\displaystyle \frac{11}{12}\)

Possible Answers:

\(\displaystyle < \)

\(\displaystyle =\)

\(\displaystyle >\)

Correct answer:

\(\displaystyle < \)

Explanation:

To compare fractions, we need to first make common denominators. 

\(\displaystyle \frac{4}{6}\times\frac{2}{2}=\frac{8}{12}\)

Now that we have common denominators, we can compare numerators. The fraction with the bigger numerator has the greater value. 

\(\displaystyle \frac{8}{12}< \frac{11}{12}\)

Example Question #43 : Extend Understanding Of Fraction Equivalence And Ordering

Select the symbol to correctly fill in the blank below. 

\(\displaystyle \frac{6}{12}\) __________\(\displaystyle \frac{3}{6}\)

Possible Answers:

\(\displaystyle < \)

\(\displaystyle >\)

\(\displaystyle =\)

Correct answer:

\(\displaystyle =\)

Explanation:

To compare fractions, we need to first make common denominators. 

\(\displaystyle \frac{3}{6}\times\frac{2}{2}=\frac{6}{12}\)

Now that we have common denominators, we can compare numerators. The fraction with the bigger numerator has the greater value. 

\(\displaystyle \frac{6}{12}=\frac{6}{12}\)

Example Question #44 : Extend Understanding Of Fraction Equivalence And Ordering

Select the symbol to correctly fill in the blank below. 

\(\displaystyle \frac{1}{2}\) __________\(\displaystyle \frac{2}{8}\)

Possible Answers:

\(\displaystyle >\)

\(\displaystyle =\)

\(\displaystyle < \)

Correct answer:

\(\displaystyle >\)

Explanation:

To compare fractions, we need to first make common denominators. 

\(\displaystyle \frac{1}{2}\times\frac{4}{4}=\frac{4}{8}\)

Now that we have common denominators, we can compare numerators. The fraction with the bigger numerator has the greater value. 

\(\displaystyle \frac{4}{8}>\frac{2}{8}\)

Example Question #45 : Extend Understanding Of Fraction Equivalence And Ordering

Select the symbol to correctly fill in the blank below. 

\(\displaystyle \frac{3}{6}\) __________\(\displaystyle \frac{12}{24}\)

Possible Answers:

\(\displaystyle =\)

\(\displaystyle >\)

\(\displaystyle < \)

Correct answer:

\(\displaystyle =\)

Explanation:

To compare fractions, we need to first make common denominators. 

\(\displaystyle \frac{3}{6}\times\frac{4}{4}=\frac{12}{24}\)

Now that we have common denominators, we can compare numerators. The fraction with the bigger numerator has the greater value. 

\(\displaystyle \frac{12}{24}=\frac{12}{24}\)

Example Question #2752 : Isee Lower Level (Grades 5 6) Quantitative Reasoning

Select the symbol to correctly fill in the blank below.  

\(\displaystyle \frac{8}{10}\) __________ \(\displaystyle \frac{3}{4}\)

Possible Answers:

\(\displaystyle >\)

\(\displaystyle < \)

\(\displaystyle =\)

Correct answer:

\(\displaystyle >\)

Explanation:

To compare fractions, we need to first make common denominators. 

\(\displaystyle \frac{8}{10}\times\frac{2}{2}=\frac{16}{20}\)

\(\displaystyle \frac{3}{4}\times\frac{5}{5}=\frac{15}{20}\)

Now that we have common denominators, we can compare numerators. The fraction with the bigger numerator has the greater value. 

\(\displaystyle \frac{8}{10}>\frac{3}{4}\)

Example Question #361 : Fractions

Select the symbol to correctly fill in the blank below.  

\(\displaystyle \frac{3}{8}\) __________ \(\displaystyle \frac{1}{5}\)

 

Possible Answers:

\(\displaystyle < \)

\(\displaystyle >\)

\(\displaystyle =\)

Correct answer:

\(\displaystyle >\)

Explanation:

To compare fractions, we need to first make common denominators. 

\(\displaystyle \frac{3}{8}\times\frac{5}{5}=\frac{15}{40}\)

\(\displaystyle \frac{1}{5}\times\frac{8}{8}=\frac{8}{40}\)

Now that we have common denominators, we can compare numerators. The fraction with the bigger numerator has the greater value. 

\(\displaystyle \frac{3}{8}>\frac{1}{5}\)

Example Question #2753 : Isee Lower Level (Grades 5 6) Quantitative Reasoning

Select the symbol to correctly fill in the blank below.  

\(\displaystyle \frac{1}{8}\) __________ \(\displaystyle \frac{1}{6}\)

 

Possible Answers:

\(\displaystyle =\)

\(\displaystyle >\)

\(\displaystyle < \)

Correct answer:

\(\displaystyle < \)

Explanation:

To compare fractions, we need to first make common denominators. 

\(\displaystyle \frac{1}{8}\times\frac{3}{3}=\frac{3}{24}\)

\(\displaystyle \frac{1}{6}\times\frac{4}{4}=\frac{4}{24}\)

Now that we have common denominators, we can compare numerators. The fraction with the bigger numerator has the greater value. 

\(\displaystyle \frac{1}{8}< \frac{1}{6}\)

Example Question #2754 : Isee Lower Level (Grades 5 6) Quantitative Reasoning

Select the symbol to correctly fill in the blank below.  

\(\displaystyle \frac{4}{10}\) __________ \(\displaystyle \frac{1}{5}\)

Possible Answers:

\(\displaystyle >\)

\(\displaystyle < \)

\(\displaystyle =\)

Correct answer:

\(\displaystyle >\)

Explanation:

To compare fractions, we need to first make common denominators. 

 

\(\displaystyle \frac{1}{5}\times\frac{2}{2}=\frac{2}{10}\)

Now that we have common denominators, we can compare numerators. The fraction with the bigger numerator has the greater value. 

\(\displaystyle \frac{4}{10}>\frac{2}{10}\)
