| Answer | Mark | Mark scheme |
|---|---|---|
| Yes (supported) | P1 | starts process to find the number of tins or meals needed, eg \(2 \times \dfrac{1}{4}\ \left(= \dfrac{2}{4} = \dfrac{1}{2}\right)\) or \(14 \times \dfrac{1}{4}\) (\(= \dfrac{14}{4}\) oe) or \(2 \times 14\ (= 28)\) or \(8 \div 2\) or to find the number of meals from 8 tins, eg \(8 \div \dfrac{1}{4}\ (= 32)\) |
| P1 | a complete process to find the number of tins needed, eg \(14 \times \dfrac{2}{4}\ (= 7)\) or \(8 \div 2\) and \(\text{``}\dfrac{14}{4}\text{''}\) OR to find the numbers of meals \(8 \div \dfrac{1}{4}\ (= 32)\) and \(2 \times 14\ (= 28)\) or \(8 \div \dfrac{2}{4}\ (= 16)\) | |
| C1 | ‘Yes’ from a comparison of correct values, eg 7 (and 8) or 32 and 28 or 16 (and 14) or \(\dfrac{14}{4}\) and 4 |
Additional guidance
Numbers may be expressed in decimal form
Correct working needs to be accompanied by a statement confirming enough food has been bought.
