| Answer | Mark | Mark scheme |
|---|---|---|
| 33 | P1 | for relating 24 to 8 parts, or (1 part =) \(24 \div 8\ (= 3)\) or \(15 - 7\ (= 8)\) or starts to use a build-up method, eg \((8 :)\ 14 : 30\) |
| P1 | for \((15 - 4)\) and \((24 \div 8)\) or \(15 \times 3\ (= 45)\) and \(4 \times 3\ (= 12)\) or for \(12\ (: 21) : 45\) | |
| A1 | cao |
