The ratio of Charlie's money to Bryan's money is 9 : 1.
The ratio of Bryan's money to Adam's money is 6 : 1.
The total amount that they have is $488.
How much more money does Charlie have than Adam?
Charlie |
Bryan |
Adam |
9 x 6 |
1 x 6 |

6 x 1 |
1 x 1 |
54 u |
6 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 6.
LCM of 1 and 6 = 6
Charlie : Bryan : Adam
54 : 6 : 1
Total amount that Charlie, Bryan and Adam have
= 54 u + 6 u + 1 u
= 61 u
61 u = 488
1 u = 488 ÷ 61 = 8
Amount that Charlie has more than Adam
= 54 u - 1 u
= 53 u
= 53 x 8
= $424
Answer(s): $424
