The ratio of Carl's to Brandon's money is 4 : 7. The ratio of Brandon's to Valen's money is 4 : 5. If Carl has $224, how much more does Valen have than Brandon?
Carl |
Brandon |
Valen |
4x4 |
7x4 |
|
|
4x7 |
5x7 |
16 u |
28 u |
35 u |
The amount that Brandon has is the repeated identity.
Use LCM to make it the same.
LCM of 7 and 4 = 28
Amount that Carl has = 16 u
16 u = 224
1 u = 224 ÷ 16 = 14
Amount that Valen has more than Brandon
= 35 u - 28 u
= 7 u
= 7 x 14
= $98
Answer(s): $98
