03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | 3 shifts | 24 divided by 8 is 3 shifts. |
| 2 | 9 hours 30 minutes | 21:30 to midnight is 2 hours 30 minutes, and 7 more hours gives 9 hours 30 minutes. |
| 3 | 85 minutes | 35 times 2 is 70, and 15 more gives 85 minutes. |
| 4 | 09:00 | Three gaps make 75 minutes, and 07:45 plus 75 minutes is 09:00. |
| 5 | 5 hours | 75 times 4 is 300 minutes, which is 5 hours. |
| 6 | 50 minutes | 200 divided by 4 is 50 minutes. |
| 7 | 7 hours 30 minutes | 08:30 to 17:15 is 8 hours 45 minutes, and taking away 75 minutes leaves 7 hours 30 minutes. |
| 8 | 01:05 the next day | 22:15 plus 1 hour 45 minutes reaches 24:00, then 65 more minutes gives 01:05. |
| 9 | 33 hours 45 minutes | 405 times 5 is 2025 minutes, which is 33 hours 45 minutes. |
| 10 | 30 minutes | 09:50 to 10:00 is 10 minutes and 10:00 to 10:20 is 20 minutes, so 30 minutes in all. |
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.
