| Before |
5x4 =
20 u |
3x3 =
9 u |
| Change |
- 2x4 =
- 8 u |
- 2x3 =
- 6 u |
| After |
3x4 =
12 u |
1x3 =
3 u |
Comparing Jaslyn
and Gwen in the end |
4x3 =
12 u |
1x3 =
3 u |
The amount that Jaslyn had in the end is repeated. Make the amount that Jaslyn had in the end the same. LCM of 4 and 3 is 12.
Amount that Jaslyn had more than Gwen
= 20 u - 9 u
= 11 u
11 u = 297
1 u = 297 ÷ 11 = 27
Amount that Gwen had at first
= 9 u
= 9 x 27
= $243
Answer(s): $243
