The ratio of Jeremy's to Ben's money is 3 : 8. The ratio of Ben's to Will's money is 3 : 4. If Jeremy has $99, how much more does Will have than Ben?
| Jeremy |
Ben |
Will |
| 3x3 |
8x3 |
|
| |
3x8 |
4x8 |
| 9 u |
24 u |
32 u |
The amount that Ben has is the repeated identity.
Use LCM to make it the same.
LCM of 8 and 3 = 24
Amount that Jeremy has = 9 u
9 u = 99
1 u = 99 ÷ 9 = 11
Amount that Will has more than Ben
= 32 u - 24 u
= 8 u
= 8 x 11
= $88
Answer(s): $88
