31 Here is some information about the members of clubs A and B.
| Number of members | Mean height of members | |
|---|---|---|
| Club A | 24 | 1.8 m |
| Club B | 20 | 1.92 m |
Work out \(\quad \dfrac{\text{total height of the members of club A}}{\text{total height of the members of club B}}\)
Give your answer as a decimal. [2 marks]
| Answer | Mark | Comments |
|---|---|---|
| \(24 \times 1.8\) or 43.2 or \(20 \times 1.92\) or 38.4 or \(\dfrac{432}{384}\) or \(\dfrac{9}{8}\) or \(1\dfrac{1}{8}\) | M1 | oe eg1 \(24 \times 180\) or 4320 eg2 \(20 \times 192\) or 3840 |
| 1.125 or 1.13 | A1 | accept 1.1 with M1 awarded |
Additional guidance
| M1 may be awarded for correct work, with no or incorrect answer, even if this is seen amongst multiple attempts | |
| Ignore attempts at rounding after correct answer seen | |
| Condone use of units in answer eg 1.125 m | M1A1 |
| \(\dfrac{9}{8} = 1.125\) on answer line | M1A1 |
| \(\dfrac{9}{8}\) and 1.125 on answer line | M1A0 |
| \(\dfrac{43.2}{38.4}\) | M1A0 |
| \(\dfrac{1.92}{1.8} = 1.1\) | M0A0 |
