The ratio of Adam's money to Bryan's money is 2 : 1.
The ratio of Bryan's money to Charlie's money is 5 : 2.
The total amount that they have is $544.
How much more money does Adam have than Charlie?

2 x 5 |
1 x 5 |

5 x 1 |
2 x 1 |
10 u |
5 u |
2 u |
Amount that Bryan has is the repeated identity.
Make the amount that Bryan has the same using the LCM of 1 and 5.
LCM of 1 and 5 = 5
Adam : Bryan : Charlie
10 : 5 : 2
Total amount that Adam, Bryan and Charlie have
= 10 u + 5 u + 2 u
= 17 u
17 u = 544
1 u = 544 ÷ 17 = 32
Amount that Adam has more than Charlie
= 10 u - 2 u
= 8 u
= 8 x 32
= $256
Answer(s): $256
