The ratio of Warren's to Jeremy's money is 3 : 7. The ratio of Jeremy's to Will's money is 4 : 5. If Warren has $132, how much more does Will have than Jeremy?
| Warren |
Jeremy |
Will |
| 3x4 |
7x4 |
|
| |
4x7 |
5x7 |
| 12 u |
28 u |
35 u |
The amount that Jeremy has is the repeated identity.
Use LCM to make it the same.
LCM of 7 and 4 = 28
Amount that Warren has = 12 u
12 u = 132
1 u = 132 ÷ 12 = 11
Amount that Will has more than Jeremy
= 35 u - 28 u
= 7 u
= 7 x 11
= $77
Answer(s): $77
