Primary 5 Maths: Division of Fractions — Practice Paper 2
Primary 5 Maths: Division of Fractions — Practice Paper 2
Paper 2 works the two directions that pupils mix up: a fraction divided by a whole number, and a whole number divided by a fraction. It starts from dividing by a unit fraction, then handles cases such as 4 divided by 2/5 and finishes with rope and juice problems.
Quick answer 10 questions, about 20 minutes. Items 01 to 03 divide fractions by whole numbers and whole numbers by unit fractions; items 04 to 06 cover 4 divided by 2/5, keeping the numerator while the denominator grows, and the length of each piece of rope; items 07 to 09 cancel before multiplying, work 5 divided by 5/6, and share a mixed-number volume into bottles; item 10 redos multiplying where the pupil should have divided.

03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | 3/8 | Dividing by 2 means multiplying by 1/2, so 3/4 x 1/2 = 3/8. |
| 2 | 5/24 | Multiply the denominator by 4: 5/24, while the numerator stays. |
| 3 | 6 | Each whole contains three thirds, so two wholes contain 6. |
| 4 | 10 | 4 divided by 2/5 is 4 x 5/2 = 20/2 = 10. |
| 5 | 7/24 | 7/8 x 1/3 = 7/24, so the denominator becomes 24. |
| 6 | 1/4 m | 3/4 divided by 3 is 3/4 x 1/3 = 3/12 = 1/4 m. |
| 7 | 3/20 | 9/10 x 1/6 = 9/60, and dividing both parts by 3 gives 3/20. |
| 8 | 6 | 5 x 6/5 = 30/5 = 6; cancelling the two 5s gives 6 at once. |
| 9 | 3/4 L | Change 2 1/4 to 9/4, then 9/4 x 1/3 = 9/12 = 3/4 L. |
| 10 | The pupil multiplied instead of dividing; the answer is 5/8 x 1/2 = 5/16 | Dividing by 2 means multiplying by 1/2, so the answer is smaller: 5/16. |
04 What to do after marking
- After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
- Repeat the same item two days later; move to the next paper only when both attempts are correct.
- Parents only need the answer and note columns; there is no need to explain every item.
