1. QuestionMultiple choice

A student reads 38\frac{3}{8} of a book on Monday and 28\frac{2}{8} on Tuesday. How much is read altogether?

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 match, so 3/8 + 2/8 = 5/8 of the book.
  3. Check the choice: The correct choice is 58\frac{5}{8}.

The denominators match, so 3/8 + 2/8 = 5/8 of the book.

2. QuestionMultiple choice

A tank is 56\frac{5}{6} full. Then 13\frac{1}{3} of the tank is used. How much remains?

Please select an answer first.

Correct answer: B

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

  1. Find a common denominator: Rewrite the fractions as equivalent fractions when their denominators are different.
  2. Calculate and simplify: Rewrite 1/3 as 2/6: 5/6 − 2/6 = 3/6 = 1/2.
  3. Check the choice: The correct choice is 12\frac{1}{2}.

Rewrite 1/3 as 2/6: 5/6 − 2/6 = 3/6 = 1/2.

3. QuestionMultiple choice

A recipe uses 1 14\frac{1}{4} cups of flour and 34\frac{3}{4} cup of oats. How many cups are used altogether?

Please select an answer first.

Correct answer: C

The correct answer is 2 cups.

  1. Find a common denominator: Rewrite the fractions as equivalent fractions when their denominators are different.
  2. Calculate and simplify: The fractional parts make one whole: 1 1/4 + 3/4 = 2 cups.
  3. Check the choice: The correct choice is 2 cups.

The fractional parts make one whole: 1 1/4 + 3/4 = 2 cups.

4. QuestionMultiple choice

A ribbon is 2 12\frac{1}{2} meters long. A piece of 34\frac{3}{4} meter is cut off. How much remains?

Please select an answer first.

Correct answer: D

The correct answer is 1 34\frac{3}{4}.

  1. Find a common denominator: Rewrite the fractions as equivalent fractions when their denominators are different.
  2. Calculate and simplify: Rewrite 2 1/2 as 2 2/4, then 2 2/4 − 3/4 requires regrouping and equals 1 3/4.
  3. Check the choice: The correct choice is 1 34\frac{3}{4}.

Rewrite 2 1/2 as 2 2/4, then 2 2/4 − 3/4 requires regrouping and equals 1 3/4.

5. QuestionMultiple choice

A hiker walks 23\frac{2}{3} mile in the morning and 56\frac{5}{6} mile in the afternoon. How far does the hiker walk?

Please select an answer first.

Correct answer: A

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

  1. Find a common denominator: Rewrite the fractions as equivalent fractions when their denominators are different.
  2. Calculate and simplify: Rewrite 2/3 as 4/6: 4/6 + 5/6 = 9/6 = 1 1/2 miles.
  3. Check the choice: The correct choice is 1 12\frac{1}{2}.

Rewrite 2/3 as 4/6: 4/6 + 5/6 = 9/6 = 1 1/2 miles.

6. QuestionMultiple choice

A board is 4 12\frac{1}{2} feet long. A piece of 1 34\frac{3}{4} feet is removed. How much remains?

Please select an answer first.

Correct answer: B

The correct answer is 2 34\frac{3}{4}.

  1. Find a common denominator: Rewrite the fractions as equivalent fractions when their denominators are different.
  2. Calculate and simplify: Rewrite 4 1/2 as 4 2/4, then 4 2/4 − 1 3/4 = 2 3/4 feet.
  3. Check the choice: The correct choice is 2 34\frac{3}{4}.

Rewrite 4 1/2 as 4 2/4, then 4 2/4 − 1 3/4 = 2 3/4 feet.

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.
