The ratio of Warren's to Owen's money is 3 : 8. The ratio of Owen's to Paul's money is 3 : 5. If Warren has $162, how much more does Paul have than Owen?
Warren |
Owen |
Paul |
3x3 |
8x3 |
|
|
3x8 |
5x8 |
9 u |
24 u |
40 u |
The amount that Owen has is the repeated identity.
Use LCM to make it the same.
LCM of 8 and 3 = 24
Amount that Warren has = 9 u
9 u = 162
1 u = 162 ÷ 9 = 18
Amount that Paul has more than Owen
= 40 u - 24 u
= 16 u
= 16 x 18
= $288
Answer(s): $288
