Ed must give Fay a total of £45 for both to have the same amount of money.
How to solve ratio
Total = £330
- Ed = 7
- Fay = 4
- Total ratio = 7 + 4
= 11
Ed share = 7/11 × 330
= £210
Fay share = 4/11 × 330
= £120
For Ed and Fay to have the same amount of money, their share must be exactly half of £330.
That is, they must each have £330/2
= £165
Fay:
£165 - £120 = £45
Therefore, Ed must give Fay a total of £45 for both to have the same amount of money.
