03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | 0.75 | Divide the numerator by the denominator: 3 divided by 4 is 0.75. |
| 2 | 60% | Multiply the decimal by 100 and add the percentage sign. |
| 3 | 40% | First make the decimal 0.4, then multiply by 100. |
| 4 | 0.125 and 12.5% | One divided by eight is 0.125, and times 100 gives 12.5. |
| 5 | 7/20 | 0.35 is 35 over 100, and dividing both by 5 gives 7 over 20. |
| 6 | 9/20 | 45% means 45 over 100, and dividing both by 5 gives 9 over 20. |
| 7 | Three quarters is larger | Three quarters is 0.75, which is bigger than 0.7. |
| 8 | 0.6, 62%, five eighths | As decimals they are 0.6, 0.62 and 0.625, so 0.6 comes first. |
| 9 | 33.3% | One divided by three is 0.3333…, which is 33.3 to one decimal place. |
| 10 | 40% | The error is shifting the point one place only; a decimal times 100 gives the percentage. |
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.
Three steps: make the denominator ten or a hundred, divide to a decimal, then multiply by a hundred for a percentage; always convert to one form before comparing or ordering.Tutor Registration →
