| Before |
8x4 =
32 u |
7x3 =
21 u |
| Change |
- 5x4 =
- 20 u |
- 6x3 =
- 18 u |
| After |
3x4 =
12 u |
1x3 =
3 u |
Comparing Mary
and Kimberly in the end |
4x3 =
12 u |
1x3 =
3 u |
The amount that Mary had in the end is repeated. Make the amount that Mary had in the end the same. LCM of 4 and 3 is 12.
Amount that Mary had more than Kimberly
= 32 u - 21 u
= 11 u
11 u = 176
1 u = 176 ÷ 11 = 16
Amount that Kimberly had at first
= 21 u
= 21 x 16
= $336
Answer(s): $336
