The ratio of Charlie's money to Bryan's money is 6 : 1.
The ratio of Bryan's money to Adam's money is 5 : 1.
The total amount that they have is $540.
How much more money does Charlie have than Adam?

6 x 5 |
1 x 5 |

5 x 1 |
1 x 1 |
30 u |
5 u |
1 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
Charlie : Bryan : Adam
30 : 5 : 1
Total amount that Charlie, Bryan and Adam have
= 30 u + 5 u + 1 u
= 36 u
36 u = 540
1 u = 540 ÷ 36 = 15
Amount that Charlie has more than Adam
= 30 u - 1 u
= 29 u
= 29 x 15
= $435
Answer(s): $435
