The ratio of Bryan's money to Adam's money is 5 : 3.
The ratio of Adam's money to Charlie's money is 6 : 5.
The total amount that they have is $546.
How much more money does Bryan have than Charlie?
Bryan |
Adam |
Charlie |
5 x 2 |
3 x 2 |

|
6 x 1 |
5 x 1 |
10 u |
6 u |
5 u |
Amount that Adam has is the repeated identity.
Make the amount that Adam has the same using the LCM of 3 and 6.
LCM of 3 and 6 = 6
Bryan : Adam : Charlie
10 : 6 : 5
Total amount that Bryan, Adam and Charlie have
= 10 u + 6 u + 5 u
= 21 u
21 u = 546
1 u = 546 ÷ 21 = 26
Amount that Bryan has more than Charlie
= 10 u - 5 u
= 5 u
= 5 x 26
= $130
Answer(s): $130
