Ahmad |
Gwen |
| Before |
4 u |
9 p |
| Change |
- 3 u |

| After |
1 u |
7 p |
Amount that Ahmad spent on the notebook = 3 u
3 u = 8.10
1 u = 8.10 ÷ 3 = 2.70
Amount that Ahmad had at first
= 4 u
= 4 x 2.70
= $10.80
Amount that Gwen had at first
= 10.80 + 53.10
= $63.90
Fraction of money that Gwen had left

29 =
79 Amount that Gwen had at first = 9 p
9 p = 63.90
