Before |
10x1 = 10 u |
5x9 = 45 u |
Change |
- 1x1 = - 1 u |
- 4x9 = - 36 u |
After |
9x1 = 9 u |
1x9 = 9 u |
0.8 =

110 Roshel and Usha had the same amount of money in the end. Make the amount that each had in the end the same. LCM of 1 and 9 is 9.
Amount that Roshel had less than Usha at first
= 45 u - 10 u
= 35 u
35 u = 595
1 u = 595 ÷ 35 = 17
Amount that Usha had at first
= 45 u
= 45 x 17
= $765
Answer(s): $765
