|
| Before |
8x3 =
24 u |
3x5 =
15 u |
| Change |
- 3x3 =
- 9 u |
- 2x5 =
- 10 u |
| After |
5x3 =
15 u |
1x5 =
5 u |
Comparing Raeann
and Min in the end |
3x5 =
15 u |
1x5 =
5 u |
The amount that Raeann had in the end is repeated. Make the amount that Raeann had in the end the same. LCM of 3 and 5 is 15.
Amount that Min had less than Raeann
= 24 u - 15 u
= 9 u
9 u = 135
1 u = 135 ÷ 9 = 15
Amount that Raeann had at first
= 24 u
= 24 x 15
= $360
Answer(s): $360
