1. QuestionMultiple choice

What is 38\frac{3}{8} + 28\frac{2}{8}?

Please select an answer first.

Correct answer: A

The correct answer is 58\frac{5}{8}.

  1. Find a common denominator: Rewrite the fractions as equivalent fractions when their denominators are different.
  2. Calculate and simplify: The denominators already match, so add the numerators: 3/8 + 2/8 = 5/8.
  3. Check the choice: The correct choice is 58\frac{5}{8}.

The denominators already match, so add the numerators: 3/8 + 2/8 = 5/8.

2. QuestionMultiple choice

Correct answer: C

The correct answer is 58\frac{5}{8}.

  1. Find a common denominator: Rewrite the fractions as equivalent fractions when their denominators are different.
  2. Calculate and simplify: Rewrite 1/4 as 2/8, then add 2/8 + 3/8 = 5/8.
  3. Check the choice: The correct choice is 58\frac{5}{8}.

Rewrite 1/4 as 2/8, then add 2/8 + 3/8 = 5/8.

4. QuestionMultiple choice

What is 56\frac{5}{6} − 13\frac{1}{3}?

Please select an answer first.

Correct answer: D

The correct answer is 12\frac{1}{2}.

  1. Find a common denominator: Rewrite the fractions as equivalent fractions when their denominators are different.

Frequently asked questions about Grade 5 Fraction Addition and Subtraction

Do you add the denominators when adding fractions?

No. Use a common denominator, then add or subtract the numerators while keeping the denominator.

Why are equivalent fractions important?

Equivalent fractions keep the same value while expressing the parts with a common denominator, which makes unlike fractions easier to combine.
