| Before |
8x4 =
32 u |
4x3 =
12 u |
| Change |
- 5x4 =
- 20 u |
- 3x3 =
- 9 u |
| After |
3x4 =
12 u |
1x3 =
3 u |
Comparing Gillian
and Kimberly in the end |
4x3 =
12 u |
1x3 =
3 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 3 is 12.
Amount that Gillian had more than Kimberly
= 32 u - 12 u
= 20 u
20 u = 700
1 u = 700 ÷ 20 = 35
Amount that Kimberly had at first
= 12 u
= 12 x 35
= $420
Answer(s): $420
