The ratio of Albert's to Ken's money is 4 : 3. The ratio of Ken's to Paul's money is 3 : 5. If Albert has $48, how much more does Paul have than Ken?
Albert |
Ken |
Paul |
4x1 |
3x1 |
|
|
3x1 |
5x1 |
4 u |
3 u |
5 u |
The amount that Ken has is the repeated identity.
Use LCM to make it the same.
LCM of 3 and 3 = 3
Amount that Albert has = 4 u
4 u = 48
1 u = 48 ÷ 4 = 12
Amount that Paul has more than Ken
= 5 u - 3 u
= 2 u
= 2 x 12
= $24
Answer(s): $24
