03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | 3/2, that is 1 1/2 | Cancel 4 with 8 to get 1 and 2, leaving 3/2. |
| 2 | 4/3, that is 1 1/3 | Divide 6 and 9 by 3 to get 2 and 3, so 2 × 2/3 = 4/3. |
| 3 | 5/2, that is 2 1/2 | Divide 6 and 12 by 6 to get 1 and 2, leaving 5/2. |
| 4 | 1/4 | Cancel 7 with 14 and 5 with 10, leaving 1/2 × 1/2 = 1/4. |
| 5 | 4 | They become 10/3 and 6/5, and 60/15 is 4. |
| 6 | 1 | As 9/4 it cancels completely with 4/9, leaving 1. |
| 7 | 3/2 m, that is 1 1/2 m | A fraction of a quantity is found by multiplying: 12/5 × 5/8 = 3/2 m. |
| 8 | 8 pupils | 36 divided by 9 is 4, and two parts give 8 pupils. |
| 9 | 1 | First 3/5 × 5/2 = 3/2, then multiplying by 2/3 gives 1. |
| 10 | 7 | The mixed number must become 7/2 first, and 7/2 × 2 is 7; multiplying only the whole part loses 1/2 × 2. |
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.
