The ratio of Asher's to John's money is 8 : 3. The ratio of John's to Ben's money is 4 : 5. If Asher has $352, how much less does John have than Ben?
| Asher |
John |
Ben |
| 8x4 |
3x4 |
|
| |
4x3 |
5x3 |
| 32 u |
12 u |
15 u |
The amount that John has is the repeated identity.
Use LCM to make it the same.
LCM of 3 and 4 = 12
Amount that Asher has = 32 u
32 u = 352
1 u = 352 ÷ 32 = 11
Amount that John has less than Ben
= 15 u - 12 u
= 3 u
= 3 x 11
= $33
Answer(s): $33
