The ratio of Asher's to Cody's money is 4 : 5. The ratio of Cody's to Brandon's money is 3 : 4. If Asher has $216, how much more does Brandon have than Cody?
| Asher |
Cody |
Brandon |
| 4x3 |
5x3 |
|
| |
3x5 |
4x5 |
| 12 u |
15 u |
20 u |
The amount that Cody has is the repeated identity.
Use LCM to make it the same.
LCM of 5 and 3 = 15
Amount that Asher has = 12 u
12 u = 216
1 u = 216 ÷ 12 = 18
Amount that Brandon has more than Cody
= 20 u - 15 u
= 5 u
= 5 x 18
= $90
Answer(s): $90
