The ratio of Michael's to Japheth's money is 3 : 5. The ratio of Japheth's to Warren's money is 3 : 5. If Michael has $144, how much less does Japheth have than Warren?
| Michael |
Japheth |
Warren |
| 3x3 |
5x3 |
|
| |
3x5 |
5x5 |
| 9 u |
15 u |
25 u |
The amount that Japheth has is the repeated identity.
Use LCM to make it the same.
LCM of 5 and 3 = 15
Amount that Michael has = 9 u
9 u = 144
1 u = 144 ÷ 9 = 16
Amount that Japheth has less than Warren
= 25 u - 15 u
= 10 u
= 10 x 16
= $160
Answer(s): $160
