The ratio of Jeremy's to Brandon's money is 3 : 8. The ratio of Brandon's to Valen's money is 3 : 4. If Jeremy has $153, how much more does Valen have than Brandon?
Jeremy |
Brandon |
Valen |
3x3 |
8x3 |
|
|
3x8 |
4x8 |
9 u |
24 u |
32 u |
The amount that Brandon has is the repeated identity.
Use LCM to make it the same.
LCM of 8 and 3 = 24
Amount that Jeremy has = 9 u
9 u = 153
1 u = 153 ÷ 9 = 17
Amount that Valen has more than Brandon
= 32 u - 24 u
= 8 u
= 8 x 17
= $136
Answer(s): $136
