| Before |
5x2 =
10 u |
4x1 =
4 u |
| Change |
- 3x2 =
- 6 u |
- 3x1 =
- 3 u |
| After |
2x2 =
4 u |
1x1 =
1 u |
Comparing Gillian
and Jade in the end |
4x1 =
4 u |
1x1 =
1 u |
The amount that Gillian had in the end is repeated. Make the amount that Gillian had in the end the same. LCM of 4 and 2 is 4.
Amount that Jade had less than Gillian
= 10 u - 4 u
= 6 u
6 u = 144
1 u = 144 ÷ 6 = 24
Amount that Gillian had at first
= 10 u
= 10 x 24
= $240
Answer(s): $240
