Before |
5x1 = 5 u |
5x2 = 10 u |
Change |
- 1x1 = - 1 u |
- 3x2 = - 6 u |
After |
4x1 = 4 u |
2x2 = 4 u |
0.6 =

15 Yen and Shannon had the same amount of money in the end. Make the amount that each had in the end the same. LCM of 2 and 4 is 4.
Amount that Yen had less than Shannon at first
= 10 u - 5 u
= 5 u
5 u = 55
1 u = 55 ÷ 5 = 11
Amount that Shannon had at first
= 10 u
= 10 x 11
= $110
Answer(s): $110
