How to Solve Word Problems Involving Dividing Fractions

To solve a dividing-fractions word problem, first decide what the quotient means: an amount in each equal share, or the number of groups of a given size. Write the division in that order, multiply by the reciprocal of the divisor, and label the answer with its units.

How to Solve Word Problems Involving Dividing Fractions

How do you know what to divide?

Equal shares: If you know the total amount and the number of equal shares, divide total amount ÷ number of shares. The answer is the amount in one share.

Groups of a given size: If you know the total amount and the size of each group, divide total amount ÷ amount per group. The answer is the number of groups. For example, finding how many 1/4-cup portions fit into 3/4 cup means 3/4 ÷ 1/4, not the other way around.

  1. Identify the total, the known group size or number of shares, and what you need to find. Use the meaning of the situation rather than one keyword.
  2. Write the division equation. Convert mixed numbers to improper fractions and write a whole-number divisor over 1.
  3. Keep the first fraction and multiply by the reciprocal of the second. The divisor must be nonzero.
  4. Simplify, attach units, and check by multiplying the answer by the divisor to recover the dividend.

Dividing fractions word problems: worked examples

1. Sharing jam equally among muffins

Karolina uses 6/8 of a jar of cherry jam to make eight muffins, with the same amount of jam in each. What fraction of the jar does each muffin contain?

We know the total amount and the number of equal shares. Divide 6/8 jar by 8 muffins.

6/8 ÷ 8 = 6/8 × 1/8 = 6/64 = 3/32

Each muffin contains 3/32 of the jar. Check: 8 × 3/32 = 24/32 = 3/4 = 6/8 jar.

2. Sharing wrapping paper equally among presents

Alice uses 4/6 of a roll of wrapping paper to wrap five presents. Each present uses the same amount. What fraction of the roll does each present use?

4/6 ÷ 5 = 4/6 × 1/5 = 4/30 = 2/15

Each present uses 2/15 of the roll. Check: 5 × 2/15 = 10/15 = 2/3 = 4/6 roll.

3. Finding how many fractional portions fit

A container holds 1 1/2 cups of oats. Each portion uses 3/8 cup. How many portions can you make?

Here the group size is known and the number of groups is unknown. Convert 1 1/2 to 3/2, then divide by 3/8.

3/2 ÷ 3/8 = 3/2 × 8/3 = 24/6 = 4

You can make 4 portions. In eighths, 1 1/2 cups is 12/8 cup; four groups of 3/8 use all 12/8. Check: 4 × 3/8 = 12/8 = 1 1/2 cups.

4. A two-step problem with leftovers

A ribbon is 2 1/4 meters long. You use 1/2 meter for a bow, then cut the rest into 3/4-meter pieces. How many complete pieces can you cut, and how much ribbon remains?

First subtract the used ribbon: 2 1/4 − 1/2 = 9/4 − 2/4 = 7/4 meters. Then divide the remaining length by the length per piece.

7/4 ÷ 3/4 = 7/4 × 4/3 = 7/3 = 2 1/3

This is 2 1/3 pieces’ worth of ribbon, so you can cut 2 complete pieces. The leftover length is 7/4 − 2 × 3/4 = 1/4 meter. The 1/3 in the quotient is a fraction of a piece, not 1/3 meter.

Common mistakes to avoid

  • Reversing the division: write down what the answer should measure before choosing the order.
  • Flipping the first fraction: take the reciprocal of the divisor only.
  • Assuming division always makes a number smaller: dividing a positive amount by a positive fraction less than 1 gives a larger numerical quotient, because the groups are smaller than one unit.
  • Rounding without reading the question: complete pieces may require rounding down; containers needed to hold everything may require rounding up. Explain any leftover in the original units.

Try three word problems

Write an equation and units before opening the worked answers. These are short on-page exercises, not a downloadable worksheet.

  1. You share 5/6 liter of juice equally among four glasses. How much juice goes in each glass?
  2. You have 2 2/3 yards of fabric. Each patch uses 2/9 yard. How many patches can you cut?
  3. You have 3 1/2 cups of flour and use 1/2 cup first. The remaining flour is for batches needing 3/4 cup each. How many batches can you make?
Show worked answers
  1. 5/6 ÷ 4 = 5/6 × 1/4 = 5/24 liter per glass. Four shares give 20/24 = 5/6 liter.
  2. 2 2/3 = 8/3. Then 8/3 ÷ 2/9 = 8/3 × 9/2 = 12 patches. Check: 12 × 2/9 = 8/3 yards.
  3. Subtract first: 3 1/2 − 1/2 = 3 cups. Then 3 ÷ 3/4 = 3 × 4/3 = 4 batches. Check: 4 × 3/4 = 3 cups.
