- Express the amount of money Eva had left as a fraction of the amount of money Carl had in the end. (Give your answer in the simplest form)

| Before |
4 u + 92 |
4 u |
| Change |
- 1 u - 23 |
- 3 u |
| After |
3 u + 69 |
1 u |
25% =
25100 =
14 75% =
75100 =
34Total amount that Carl and Eva had in the end
= 3 u + 69 + 1 u
= 4 u + 69
4 u + 69 = 297
3 u + 1 u = 297 - 69
4 u = 228
1 u = 228 ÷ 4 = 57
Amount that Carl had in the end
= 3 u + 69
= 3 x 57 + 69
= 171 + 69
= $240
(b)
Amount that the Eva had in the end
= 1 u
= $57
Fraction of the amount that Eva had left as a fraction of the amount that Carl had in the end
