The ratio of Perry's to Valen's money is 3 : 8. The ratio of Valen's to Lee's money is 3 : 4. If Perry has $117, how much more does Lee have than Valen?
Perry |
Valen |
Lee |
3x3 |
8x3 |
|
|
3x8 |
4x8 |
9 u |
24 u |
32 u |
The amount that Valen has is the repeated identity.
Use LCM to make it the same.
LCM of 8 and 3 = 24
Amount that Perry has = 9 u
9 u = 117
1 u = 117 ÷ 9 = 13
Amount that Lee has more than Valen
= 32 u - 24 u
= 8 u
= 8 x 13
= $104
Answer(s): $104
