03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | 142 members added, about 278.4 per cent | Subtract 51 from 193 to get 142, then divide by 51; the answer is not 278 members. |
| 2 | 33.3 per cent | Five divided by fifteen, rounded to one decimal place. |
| 3 | 370.4 kilometres | Two hundred times 1.852; do not confuse it with the 12 nautical mile territorial sea. |
| 4 | 79.5 per cent | Thirty-five divided by forty-four; the high share shows where peacekeeping activity concentrated. |
| 5 | 112.5 per cent | The nine extra goals divided by the original eight; this is a rate, not a count. |
| 6 | 120 days | Four days left in June, then 31 in July, 31 in August, 30 in September and 24 in October. |
| 7 | 129 votes | Two thirds of 193 is 128.67, so the minimum whole number is 129. |
| 8 | a 2 year term; 33.3 per cent of seats turn over each year | Ten seats rotate in two batches of five, so the term is two years; five divided by fifteen gives the annual share. |
| 9 | because the difference between 1.5 and 2 degrees is marked for coral reefs, food supply and coastal risk | What matters is the chance of crossing thresholds, not the neatness of the number. |
| 10 | wrong: an amendment needs two thirds in the Assembly and ratification by two thirds of members including every permanent member | The permanent five can block reform at the ratification stage, which is central to the design. |
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.
Write the formula, substitute, then check the unit.Tutor Registration →
