|---|---|---|---|
| \(3 : 8\) | 2 | M1 for correct partial simplification of \(75 : 200\) | e.g. \(15 : 40\) but not e.g. \(37.5 : 100\) \(1 : 2\frac{2}{3}\) scores M1 |

| 150 | 2 | M1 for \(18 \div 12 \times 100\) oe | |
| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| Answer of 54 | 4 | M3 for \(225 \div 50 \times 12\) oe or B2 for 60 or 9 [eggs] and 225 or M1 for \(225 \div 50\) or \(10 \div 2\) soi | For M3 allow a table with just one error |
