The ratio of Bryan's money to Charlie's money is 6 : 2.
The ratio of Charlie's money to Adam's money is 8 : 6.
The total amount that they have is $266.
How much less money does Adam have than Bryan?

6 x 4 |
2 x 4 |

8 x 1 |
6 x 1 |
24 u |
8 u |
6 u |
Amount that Charlie has is the repeated identity.
Make the amount that Charlie has the same using the LCM of 2 and 8.
LCM of 2 and 8 = 8
Bryan : Charlie : Adam
24 : 8 : 6
Total amount that Bryan, Charlie and Adam have
= 24 u + 8 u + 6 u
= 38 u
38 u = 266
1 u = 266 ÷ 38 = 7
Amount that Adam has less than Bryan
= 24 u - 6 u
= 18 u
= 18 x 7
= $126
Answer(s): $126
