Grade 4 Adding and Subtracting Fractions Practice Test

Correct answer: A

The correct answer is $\frac{4}{8}$.

1. Identify the common denominator: The fractions already have like denominators, so the parts are the same size.
2. Add or subtract the numerators: Subtract 3 from 7 and keep denominator 8: $\frac{7}{8}$ - $\frac{3}{8}$ = $\frac{4}{8}$.
3. Keep the denominator: The denominator stays the same, so the correct choice is $\frac{4}{8}$.

Correct answer: B

The correct answer is $\frac{5}{10}$.

1. Identify the common denominator: The fractions already have like denominators, so the parts are the same size.
2. Add or subtract the numerators: Subtract the numerators 9 and 4 to get 5, with denominator 10.
3. Keep the denominator: The denominator stays the same, so the correct choice is $\frac{5}{10}$.

Correct answer: C

The correct answer is $\frac{6}{12}$.

1. Identify the common denominator: The fractions already have like denominators, so the parts are the same size.
2. Add or subtract the numerators: Eleven minus five is six, so the difference is $\frac{6}{12}$.
3. Keep the denominator: The denominator stays the same, so the correct choice is $\frac{6}{12}$.

Correct answer: D

The correct answer is $\frac{6}{9}$.

1. Identify the common denominator: The fractions already have like denominators, so the parts are the same size.
2. Add or subtract the numerators: Subtract 2 from 8 and keep denominator 9.
3. Keep the denominator: The denominator stays the same, so the correct choice is $\frac{6}{9}$.

Correct answer: A

The correct answer is $\frac{5}{7}$.

1. Identify the common denominator: The fractions already have like denominators, so the parts are the same size.
2. Add or subtract the numerators: Six sevenths minus one seventh is five sevenths.
3. Keep the denominator: The denominator stays the same, so the correct choice is $\frac{5}{7}$.

Correct answer: B

The correct answer is $\frac{9}{15}$.

1. Identify the common denominator: The fractions already have like denominators, so the parts are the same size.
2. Add or subtract the numerators: Subtract 4 from 13 to get 9, and keep denominator 15.
3. Keep the denominator: The denominator stays the same, so the correct choice is $\frac{9}{15}$.

Correct answer: C

The correct answer is $\frac{7}{11}$.

1. Identify the common denominator: The fractions already have like denominators, so the parts are the same size.
2. Add or subtract the numerators: Ten minus three is seven, so the difference is $\frac{7}{11}$.
3. Keep the denominator: The denominator stays the same, so the correct choice is $\frac{7}{11}$.

Correct answer: D

The correct answer is $\frac{9}{16}$.

1. Identify the common denominator: The fractions already have like denominators, so the parts are the same size.
2. Add or subtract the numerators: Subtract the numerators 14 and 5 and keep denominator 16.
3. Keep the denominator: The denominator stays the same, so the correct choice is $\frac{9}{16}$.

Correct answer: A

The correct answer is $\frac{3}{6}$.

1. Identify the common denominator: The fractions already have like denominators, so the parts are the same size.
2. Add or subtract the numerators: Five sixths minus two sixths is three sixths.
3. Keep the denominator: The denominator stays the same, so the correct choice is $\frac{3}{6}$.

Correct answer: B

The correct answer is $\frac{2}{13}$.

1. Identify the common denominator: The fractions already have like denominators, so the parts are the same size.
2. Add or subtract the numerators: Nine minus seven is two, so the difference is $\frac{2}{13}$.
3. Keep the denominator: The denominator stays the same, so the correct choice is $\frac{2}{13}$.
