Possible Answers:

$\frac{3}{19}$

$\frac{4}{11}$

$\frac{3}{28}$

$\frac{19}{28}$

Correct answer:

$\frac{19}{28}$

Explanation:

The least common denominator of and is .

$\frac{1}{4}=\frac{7}{28}$

$\frac{3}{7}=\frac{12}{28}$

$\frac{7}{28}+\frac{12}{28}=\frac{19}{28}$

Example Question #423 : Arithmetic

Add the fractions below.

$\frac{4}{5} + \frac{7}{10}$

Possible Answers:

$\frac{11}{10}$

$\frac{9}{5}$

$\frac{11}{15}$

$\frac{3}{2}$

$\frac{18}{5}$

Correct answer:

$\frac{3}{2}$

Explanation:

First, we need to find a common denominator. In this case, we can convert both denominators to .

$\frac{4}{5} + \frac{7}{10} = (\frac{4 }{5 }*\frac{2}{2}) + \frac{7}{10} = \frac{8}{10} + \frac{7}{10}$

Now we can add the numerators.

$\frac{8}{10}+\frac{7}{10}=\frac{15}{10}$

Both the numerator and denominator are divisible by , so we can simplify.

$\frac{15}{10}= \frac{15\div 5}{10\div 5}= \frac{3}{2}$

Example Question #424 : Arithmetic

Add: $\frac{15}{24}+\frac{8}{24}=$

Possible Answers:

$\frac{23}{24}$

$\frac{7}{24}$

Correct answer:

$\frac{23}{24}$

Explanation:

To solve, add the numerators and leave the denominators the same:

$\frac{15}{24}+\frac{8}{24}=\frac{23}{24}$

Answer: $\frac{23}{24}$

Example Question #1372 : Ssat Middle Level Quantitative (Math)

Solve the equation.

$\frac{5}{10}+\frac{2}{10}=$

Possible Answers:

$\frac{3}{10}$

$\frac{3}{5}$

$\frac{7}{10}$

$\frac{2}{10}$

Correct answer:

$\frac{7}{10}$

Explanation:

When adding fractions that have the same denominator, only the numerators are added together. Add the numerators and keep the denominators:

$\frac{5}{10}+\frac{2}{10}=\frac{7}{10}$

Answer: $\frac{7}{10}$

Example Question #1021 : Hspt Mathematics

Solve the equation:

$\frac{25}{70}+\frac{10}{70}=$

Possible Answers:

$\frac{1}{2}$

$\frac{15}{70}$

$\frac{3}{7}$

Correct answer:

$\frac{1}{2}$

Explanation:

When adding fractions that have the same denominator, only the numerators are added together. Add the numerators and keep the denominators:

$\frac{25}{70}+\frac{10}{70}=\frac{35}{70}$

This fraction can be reduced by dividing both the numerator and denominator by a common factor.

$\frac{35}{70}=\frac{35\div35}{70\div35}=\frac{1}{2}$

Answer: $\frac{1}{2}$
