| Before |
4 u + 56 |
4 u |
| Change |
- 1 u - 14 |
- 3 u |
| After |
3 u + 42 |
1 u |
25% =
25100 =
14 75% =
75100 =
34Total amount that Lee and Gem had in the end
= 3 u + 42 + 1 u
= 4 u + 42
4 u + 42 = 350
3 u + 1 u = 350 - 42
4 u = 308
1 u = 308 ÷ 4 = 77
Amount that Lee had in the end
= 3 u + 42
= 3 x 77 + 42
= 231 + 42
= $273

Amount that the Gem had in the end
= 1 u
= $77
Fraction of the amount that Gem had left as a fraction of the amount that Lee had in the end
