The ratio of Japheth's to Albert's money is 5 : 8. The ratio of Albert's to Jeremy's money is 3 : 4. If Japheth has $285, how much less does Albert have than Jeremy?
| Japheth |
Albert |
Jeremy |
| 5x3 |
8x3 |
|
| |
3x8 |
4x8 |
| 15 u |
24 u |
32 u |
The amount that Albert has is the repeated identity.
Use LCM to make it the same.
LCM of 8 and 3 = 24
Amount that Japheth has = 15 u
15 u = 285
1 u = 285 ÷ 15 = 19
Amount that Albert has less than Jeremy
= 32 u - 24 u
= 8 u
= 8 x 19
= $152
Answer(s): $152
