45 of his pay and Gabriel saved
37 of his pay. Charlie saved $180 more than Gabriel in a month. How much did Gabriel save in a month?

Charlie |
Gabriel |
Before |
5x7 = 35 u |
7x5 = 35 u |
Change |
- 4x7 = - 28 u |
- 3x5 = - 15 u |
After |
1x7 = 7 u |
4x5 = 20 u |
The amount that Charlie and Gabriel each earned in a month is the same. Make the amount the same. LCM of 5 and 7 is 35.
Amount that Charlie saved more than Gabriel
= 28 u - 15 u
= 13 u
13 u = 180
1 u = 180 ÷ 13 = 180
Amount that Gabriel saved in a month
= 15 u
= 15 x 180
= $2700
Answer(s): $2700
