The ratio of Charlie's money to Adam's money is 3 : 2.
The ratio of Adam's money to Bryan's money is 3 : 2.
The total amount that they have is $133.
How much more money does Charlie have than Bryan?
Charlie |
Adam |
Bryan |
3 x 3 |
2 x 3 |

|
3 x 2 |
2 x 2 |
9 u |
6 u |
4 u |
Amount that Adam has is the repeated identity.
Make the amount that Adam has the same using the LCM of 2 and 3.
LCM of 2 and 3 = 6
Charlie : Adam : Bryan
9 : 6 : 4
Total amount that Charlie, Adam and Bryan have
= 9 u + 6 u + 4 u
= 19 u
19 u = 133
1 u = 133 ÷ 19 = 7
Amount that Charlie has more than Bryan
= 9 u - 4 u
= 5 u
= 5 x 7
= $35
Answer(s): $35
