The ratio of Howard's to John's money is 8 : 3. The ratio of John's to Reggie's money is 3 : 5. If Howard has $136, how much more does Reggie have than John?
| Howard |
John |
Reggie |
| 8x1 |
3x1 |
|
| |
3x1 |
5x1 |
| 8 u |
3 u |
5 u |
The amount that John has is the repeated identity.
Use LCM to make it the same.
LCM of 3 and 3 = 3
Amount that Howard has = 8 u
8 u = 136
1 u = 136 ÷ 8 = 17
Amount that Reggie has more than John
= 5 u - 3 u
= 2 u
= 2 x 17
= $34
Answer(s): $34
