Primary 5 Maths: Mixed Fraction Multiplication and Division — Practice Paper 4 (10 Questions)
Paper 4 asks which quantity is the whole: work back from a part to the whole, multiply when a fraction is taken of a fraction, and finish with left-to-right order again.
Quick answer 10 questions, about 25 minutes. Items 06 and 07 work back from a part to the whole, item 08 turns a fraction into an area unit, item 10 checks order only; mark after finishing.

03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | 3/4 | Cancel first: 5 with 10 gives 1 and 2, 9 with 6 gives 3 and 2, so 3/4. |
| 2 | 1 1/3 | Flip the divisor: 7/8 × 32/21, which cancels to 4/3, or 1 1/3. |
| 3 | 2 | Both become improper: 8/3 ÷ 4/3 = 8/3 × 3/4 = 2. |
| 4 | 15 | An integer divided by a fraction: flip and multiply, 9 × 5/3 = 15. |
| 5 | 1 | Left to right: 4/9 × 3/8 = 1/6, then ÷ 1/6 = 1. |
| 6 | 2/5 | The word of means a second taking, so multiply: 3/5 × 2/3 = 2/5, not add or subtract. |
| 7 | 40 L | The remainder is 1 − 3/8 = 5/8 of the whole; part to whole means divide: 25 ÷ 5/8 = 40. |
| 8 | 1/2 m² | Length × width = 4/5 × 5/8; the two 5s cancel, leaving 1/2 m². |
| 9 | 117/160 | Work out 6/5 and 15/32 first, then subtract on 160ths: 192/160 − 75/160. |
| 10 | 1 1/3 | Multiplication and division rank equally, so go left to right: 5/6 × 12/5 = 2, then × 2/3 = 4/3. |
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.
