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

|
3 x 2 |
2 x 2 |
9 u |
6 u |
4 u |
Amount that Charlie has is the repeated identity.
Make the amount that Charlie has the same using the LCM of 2 and 3.
LCM of 2 and 3 = 6
Bryan : Charlie : Adam
9 : 6 : 4
Total amount that Bryan, Charlie and Adam have
= 9 u + 6 u + 4 u
= 19 u
19 u = 589
1 u = 589 ÷ 19 = 31
Amount that Bryan has more than Adam
= 9 u - 4 u
= 5 u
= 5 x 31
= $155
Answer(s): $155
