The ratio of Charlie's money to Adam's money is 5 : 3.
The ratio of Adam's money to Bryan's money is 7 : 6.
The total amount that they have is $296.
How much more money does Charlie have than Bryan?
Charlie |
Adam |
Bryan |
5 x 7 |
3 x 7 |

|
7 x 3 |
6 x 3 |
35 u |
21 u |
18 u |
Amount that Adam has is the repeated identity.
Make the amount that Adam has the same using the LCM of 3 and 7.
LCM of 3 and 7 = 21
Charlie : Adam : Bryan
35 : 21 : 18
Total amount that Charlie, Adam and Bryan have
= 35 u + 21 u + 18 u
= 74 u
74 u = 296
1 u = 296 ÷ 74 = 4
Amount that Charlie has more than Bryan
= 35 u - 18 u
= 17 u
= 17 x 4
= $68
Answer(s): $68
