23 of his pay and Ryan saved
27 of his pay. Andy saved $160 more than Ryan in a month. How much did Ryan save in a month?

Andy |
Ryan |
Before |
3x7 = 21 u |
7x3 = 21 u |
Change |
- 2x7 = - 14 u |
- 2x3 = - 6 u |
After |
1x7 = 7 u |
5x3 = 15 u |
The amount that Andy and Ryan each earned in a month is the same. Make the amount the same. LCM of 3 and 7 is 21.
Amount that Andy saved more than Ryan
= 14 u - 6 u
= 8 u
8 u = 160
1 u = 160 ÷ 8 = 160
Amount that Ryan saved in a month
= 6 u
= 6 x 160
= $960
Answer(s): $960
