Answer 180, 260 and 360
Step-by-step explanation
Eli age = 9
Freda age = 13
Geoff age = 18
We write the ages in ratio as 9 : 13 : 18
Now sum all the ages 9 + 13 + 18 = 40
The total amount to be shared is £800
Therefore Eli share = 9/40 x £800 = £180
Freda share = 13/40 x £800 = £260
Geoff share = 18/40 x £800 = £360
