The ratio of Adam's money to Bryan's money is 9 : 4.
The ratio of Bryan's money to Charlie's money is 8 : 3.
The total amount that they have is $232.
How much more money does Adam have than Charlie?
Adam |
Bryan |
Charlie |
9 x 2 |
4 x 2 |

|
8 x 1 |
3 x 1 |
18 u |
8 u |
3 u |
Amount that Bryan has is the repeated identity.
Make the amount that Bryan has the same using the LCM of 4 and 8.
LCM of 4 and 8 = 8
Adam : Bryan : Charlie
18 : 8 : 3
Total amount that Adam, Bryan and Charlie have
= 18 u + 8 u + 3 u
= 29 u
29 u = 232
1 u = 232 ÷ 29 = 8
Amount that Adam has more than Charlie
= 18 u - 3 u
= 15 u
= 15 x 8
= $120
Answer(s): $120
