The ratio of Charlie's money to Bryan's money is 5 : 3.
The ratio of Bryan's money to Adam's money is 8 : 1.
The total amount that they have is $134.
How much more money does Charlie have than Adam?
Charlie |
Bryan |
Adam |
5 x 8 |
3 x 8 |

8 x 3 |
1 x 3 |
40 u |
24 u |
3 u |
Amount that Bryan has is the repeated identity.
Make the amount that Bryan has the same using the LCM of 3 and 8.
LCM of 3 and 8 = 24
Charlie : Bryan : Adam
40 : 24 : 3
Total amount that Charlie, Bryan and Adam have
= 40 u + 24 u + 3 u
= 67 u
67 u = 134
1 u = 134 ÷ 67 = 2
Amount that Charlie has more than Adam
= 40 u - 3 u
= 37 u
= 37 x 2
= $74
Answer(s): $74
