How it works: a quick refresher
The rules this worksheet practices, then one problem worked from start to finish.
| Strategy | How it works |
|---|---|
| Sharing a fraction | 1/3 ÷ 4 shares one third into 4 equal parts. Each part is 1/12. |
| How many fit | 4 ÷ 1/5 asks how many fifths fit in 4. There are 5 in each whole, so 4 × 5 = 20. |
| Check with multiplication | 1/12 × 4 = 4/12 = 1/3, and 20 × 1/5 = 4. |
| The answer's size | Dividing by a whole number makes a fraction smaller. Dividing by a unit fraction gives a bigger number. |
Worked example
Find 3 ÷ 1/4.
- 1Ask how many fourths fit in 3.
- 2Each whole has 4 fourths.
- 33 wholes have 3 × 4 = 12 fourths, so 3 ÷ 1/4 = 12.
- 4Check: 12 × 1/4 = 12/4 = 3.

Common questions
- Is there an answer key?
- Yes. Every worksheet has a matching answer key with each answer worked on the same grid or layout as the question. The worksheet code printed at the bottom of each page pairs a sheet with its key.
- Why is 4 ÷ 1/5 bigger than 4?
- Dividing asks how many groups fit. A fifth is small, so many fifths fit in 4: twenty of them. The smaller the piece, the more pieces fit.
- Should my child use invert and multiply?
- Grade 5 builds the meaning first: sharing a fraction, or counting how many pieces fit. The shortcut comes in grade 6, and it gives the same answers.
- How many different versions are there?
- About a million per skill. Each time you press the button the problems are generated fresh, so you can print a different version for every student, a retake, or another night of practice.
- Are the worksheets free?
- Yes. They are free to print and copy for your home or classroom, with no sign-up.
