The ratio of Bryan's money to Charlie's money is 5 : 3.
The ratio of Charlie's money to Adam's money is 6 : 2.
The total amount that they have is $576.
How much less money does Adam have than Bryan?
Bryan |
Charlie |
Adam |
5 x 2 |
3 x 2 |

|
6 x 1 |
2 x 1 |
10 u |
6 u |
2 u |
Amount that Charlie has is the repeated identity.
Make the amount that Charlie has the same using the LCM of 3 and 6.
LCM of 3 and 6 = 6
Bryan : Charlie : Adam
10 : 6 : 2
Total amount that Bryan, Charlie and Adam have
= 10 u + 6 u + 2 u
= 18 u
18 u = 576
1 u = 576 ÷ 18 = 32
Amount that Adam has less than Bryan
= 10 u - 2 u
= 8 u
= 8 x 32
= $256
Answer(s): $256
