The ratio of Cody's to Julian's money is 5 : 6. The ratio of Julian's to Liam's money is 3 : 4. If Cody has $60, how much more does Liam have than Julian?
| Cody |
Julian |
Liam |
| 5x1 |
6x1 |
|
| |
3x2 |
4x2 |
| 5 u |
6 u |
8 u |
The amount that Julian has is the repeated identity.
Use LCM to make it the same.
LCM of 6 and 3 = 6
Amount that Cody has = 5 u
5 u = 60
1 u = 60 ÷ 5 = 12
Amount that Liam has more than Julian
= 8 u - 6 u
= 2 u
= 2 x 12
= $24
Answer(s): $24
