The ratio of Bryan's money to Adam's money is 5 : 2.
The ratio of Adam's money to Charlie's money is 8 : 3.
The total amount that they have is $589.
How much more money does Bryan have than Charlie?
Bryan |
Adam |
Charlie |
5 x 4 |
2 x 4 |

|
8 x 1 |
3 x 1 |
20 u |
8 u |
3 u |
Amount that Adam has is the repeated identity.
Make the amount that Adam has the same using the LCM of 2 and 8.
LCM of 2 and 8 = 8
Bryan : Adam : Charlie
20 : 8 : 3
Total amount that Bryan, Adam and Charlie have
= 20 u + 8 u + 3 u
= 31 u
31 u = 589
1 u = 589 ÷ 31 = 19
Amount that Bryan has more than Charlie
= 20 u - 3 u
= 17 u
= 17 x 19
= $323
Answer(s): $323
