45 of his pay and Liam saved
47 of his pay. Cody saved $160 more than Liam in a month. How much did Liam save in a month?

Cody |
Liam |
Before |
5x7 = 35 u |
7x5 = 35 u |
Change |
- 4x7 = - 28 u |
- 4x5 = - 20 u |
After |
1x7 = 7 u |
3x5 = 15 u |
The amount that Cody and Liam each earned in a month is the same. Make the amount the same. LCM of 5 and 7 is 35.
Amount that Cody saved more than Liam
= 28 u - 20 u
= 8 u
8 u = 160
1 u = 160 ÷ 8 = 160
Amount that Liam saved in a month
= 20 u
= 20 x 160
= $3200
Answer(s): $3200
