| 225.5 ÷ 82 × “86” or 225.5 ÷ 22.7.. × 23.8… or digits 236… or “473” ÷ 2 | M1 |

Notes
M1: Accept digits 2255(000…) in place of 225.5 in both method marks
M1: (dep) for complete method
(NB: 82 and 86 may be converted to percentage of 360 – and then these percentages used
\(\dfrac{82}{360} = 22.7..\%\) or 23%; \(\dfrac{86}{360} = 23.8..\%\) or 24%)
A1: oe accept 236.5 million or 236 500 000
