The ratio of Eric's to Jeremy's money is 5 : 8. The ratio of Jeremy's to Oliver's money is 3 : 4. If Eric has $300, how much more does Oliver have than Jeremy?
Eric |
Jeremy |
Oliver |
5x3 |
8x3 |
|
|
3x8 |
4x8 |
15 u |
24 u |
32 u |
The amount that Jeremy has is the repeated identity.
Use LCM to make it the same.
LCM of 8 and 3 = 24
Amount that Eric has = 15 u
15 u = 300
1 u = 300 ÷ 15 = 20
Amount that Oliver has more than Jeremy
= 32 u - 24 u
= 8 u
= 8 x 20
= $160
Answer(s): $160
