The ratio of Wesley's to George's money is 3 : 5. The ratio of George's to Tommy's money is 3 : 4. If Wesley has $171, how much less does George have than Tommy?
| Wesley |
George |
Tommy |
| 3x3 |
5x3 |
|
| |
3x5 |
4x5 |
| 9 u |
15 u |
20 u |
The amount that George has is the repeated identity.
Use LCM to make it the same.
LCM of 5 and 3 = 15
Amount that Wesley has = 9 u
9 u = 171
1 u = 171 ÷ 9 = 19
Amount that George has less than Tommy
= 20 u - 15 u
= 5 u
= 5 x 19
= $95
Answer(s): $95
