The ratio of Adam's money to Bryan's money is 5 : 2.
The ratio of Bryan's money to Charlie's money is 6 : 5.
The total amount that they have is $598.
How much less money does Charlie have than Adam?

Bryan |
Charlie |
5 x 3 |
2 x 3 |

6 x 1 |
5 x 1 |
15 u |
6 u |
5 u |
Amount that Bryan has is the repeated identity.
Make the amount that Bryan has the same using the LCM of 2 and 6.
LCM of 2 and 6 = 6
Adam : Bryan : Charlie
15 : 6 : 5
Total amount that Adam, Bryan and Charlie have
= 15 u + 6 u + 5 u
= 26 u
26 u = 598
1 u = 598 ÷ 26 = 23
Amount that Charlie has less than Adam
= 15 u - 5 u
= 10 u
= 10 x 23
= $230
Answer(s): $230
