Grade 4 Adding and Subtracting Fractions Practice Test

Correct answer: A

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: Add the numerators 2 and 4 and keep denominator 9.
3. Keep the denominator: The denominator stays the same, so the correct choice is $\frac{6}{9}$.

Correct answer: B

The correct answer is $\frac{7}{8}$.

1. Identify the common denominator: The fractions already have like denominators, so the parts are the same size.
2. Add or subtract the numerators: Five eighths plus two eighths equals seven eighths.
3. Keep the denominator: The denominator stays the same, so the correct choice is $\frac{7}{8}$.

Correct answer: C

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 4 tenths from 9 tenths to get 5 tenths.
3. Keep the denominator: The denominator stays the same, so the correct choice is $\frac{5}{10}$.

Correct answer: D

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

1. Identify the common denominator: The fractions already have like denominators, so the parts are the same size.
2. Add or subtract the numerators: Three fourths plus one fourth makes four fourths, or one whole.
3. Keep the denominator: The denominator stays the same, so the correct choice is $\frac{4}{4}$.

Correct answer: A

The correct answer is $\frac{2}{6}$ + $\frac{3}{6}$ = $\frac{5}{6}$.

1. Identify the common denominator: The fractions already have like denominators, so the parts are the same size.
2. Add or subtract the numerators: Two sixths plus three sixths equals five sixths.
3. Keep the denominator: The denominator stays the same, so the correct choice is $\frac{2}{6}$ + $\frac{3}{6}$ = $\frac{5}{6}$.

Correct answer: B

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: Subtract 5 twelfths from 11 twelfths to get 6 twelfths.
3. Keep the denominator: The denominator stays the same, so the correct choice is $\frac{6}{12}$.

Correct answer: C

The correct answer is $\frac{8}{9}$ - $\frac{3}{9}$.

1. Identify the common denominator: The fractions already have like denominators, so the parts are the same size.
2. Add or subtract the numerators: Both fractions in the correct expression have denominator 9, and the operation is subtraction.
3. Keep the denominator: The denominator stays the same, so the correct choice is $\frac{8}{9}$ - $\frac{3}{9}$.

Correct answer: D

The correct answer is $\frac{7}{10}$.

1. Identify the common denominator: The fractions already have like denominators, so the parts are the same size.
2. Add or subtract the numerators: Add two tenths and five tenths to get seven tenths.
3. Keep the denominator: The denominator stays the same, so the correct choice is $\frac{7}{10}$.

Correct answer: A

The correct answer is $\frac{5}{8}$.

1. Identify the common denominator: The fractions already have like denominators, so the parts are the same size.
2. Add or subtract the numerators: Four eighths plus one eighth equals five eighths.
3. Keep the denominator: The denominator stays the same, so the correct choice is $\frac{5}{8}$.

Correct answer: B

The correct answer is $\frac{7}{13}$.

1. Identify the common denominator: The fractions already have like denominators, so the parts are the same size.
2. Add or subtract the numerators: Subtract 3 thirteenths from 10 thirteenths to get 7 thirteenths.
3. Keep the denominator: The denominator stays the same, so the correct choice is $\frac{7}{13}$.
