The ratio of Ethan's to Daniel's money is 5 : 6. The ratio of Daniel's to Sam's money is 3 : 4. If Ethan has $70, how much more does Sam have than Daniel?
| Ethan |
Daniel |
Sam |
| 5x1 |
6x1 |
|
| |
3x2 |
4x2 |
| 5 u |
6 u |
8 u |
The amount that Daniel has is the repeated identity.
Use LCM to make it the same.
LCM of 6 and 3 = 6
Amount that Ethan has = 5 u
5 u = 70
1 u = 70 ÷ 5 = 14
Amount that Sam has more than Daniel
= 8 u - 6 u
= 2 u
= 2 x 14
= $28
Answer(s): $28
