The ratio of Caden's to Japheth's money is 4 : 3. The ratio of Japheth's to Ben's money is 3 : 5. If Caden has $76, how much less does Japheth have than Ben?
| Caden |
Japheth |
Ben |
| 4x1 |
3x1 |
|
| |
3x1 |
5x1 |
| 4 u |
3 u |
5 u |
The amount that Japheth has is the repeated identity.
Use LCM to make it the same.
LCM of 3 and 3 = 3
Amount that Caden has = 4 u
4 u = 76
1 u = 76 ÷ 4 = 19
Amount that Japheth has less than Ben
= 5 u - 3 u
= 2 u
= 2 x 19
= $38
Answer(s): $38
