The ratio of Gabriel's to Jeremy's money is 7 : 4. The ratio of Jeremy's to Wesley's money is 3 : 5. If Gabriel has $210, how much less does Jeremy have than Wesley?
| Gabriel |
Jeremy |
Wesley |
| 7x3 |
4x3 |
|
| |
3x4 |
5x4 |
| 21 u |
12 u |
20 u |
The amount that Jeremy has is the repeated identity.
Use LCM to make it the same.
LCM of 4 and 3 = 12
Amount that Gabriel has = 21 u
21 u = 210
1 u = 210 ÷ 21 = 10
Amount that Jeremy has less than Wesley
= 20 u - 12 u
= 8 u
= 8 x 10
= $80
Answer(s): $80
