(a) Write an expression for the weight, in grams, of an object weighing \(x\) kilograms. [1]
(b) Write an expression for the area, in m2, of a garden of area \(y\) cm2. [1]
| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| \(1000x\) oe or \(x\) kg = \(1000x\) oe | 1 | Accept e.g. \(1000 \times x\) or \(x1000\) or \(x \times 1000\) Do not allow e.g. \(x = 1000x\) or \(w = x1000\) Ignore units e.g. k and g | |

|---|---|---|---|
| \(\frac{y}{10\,000}\) oe or \(y\) cm2 = \(\frac{y}{10\,000}\) oe | 1 | Allow e.g. \(\frac{y}{100^2}\) or \(0.0001y\) or \(y \times 10^{-4}\) or \(y \div 10\,000\) or \(0.0001 \times y\) or \(\frac{1}{10000}y\) Ignore units e.g. m and cm | |
