The ratio of Jeremy's to Ken's money is 4 : 9. The ratio of Ken's to Howard's money is 3 : 5. If Jeremy has $56, how much more does Howard have than Ken?
Jeremy |
Ken |
Howard |
4x1 |
9x1 |
|
|
3x3 |
5x3 |
4 u |
9 u |
15 u |
The amount that Ken has is the repeated identity.
Use LCM to make it the same.
LCM of 9 and 3 = 9
Amount that Jeremy has = 4 u
4 u = 56
1 u = 56 ÷ 4 = 14
Amount that Howard has more than Ken
= 15 u - 9 u
= 6 u
= 6 x 14
= $84
Answer(s): $84
