Reggie and Liam earned the same amount each month. Reggie saved
34 of his pay and Liam saved
25 of his pay. Reggie saved $120 more than Liam in a month. How much did Liam save in a month?

Reggie |
Liam |
Before |
4x5 = 20 u |
5x4 = 20 u |
Change |
- 3x5 = - 15 u |
- 2x4 = - 8 u |
After |
1x5 = 5 u |
3x4 = 12 u |
The amount that Reggie and Liam each earned in a month is the same. Make the amount the same. LCM of 4 and 5 is 20.
Amount that Reggie saved more than Liam
= 15 u - 8 u
= 7 u
7 u = 120
1 u = 120 ÷ 7 = 120
Amount that Liam saved in a month
= 8 u
= 8 x 120
= $960
Answer(s): $960
