The ratio of Charlie's money to Adam's money is 8 : 3.
The ratio of Adam's money to Bryan's money is 9 : 5.
The total amount that they have is $418.
How much less money does Bryan have than Charlie?
Charlie |
Adam |
Bryan |
8 x 3 |
3 x 3 |
|
|
9 x 1 |
5 x 1 |
24 u |
9 u |
5 u |
Amount that Adam has is the repeated identity.
Make the amount that Adam has the same using the LCM of 3 and 9.
LCM of 3 and 9 = 9
Charlie : Adam : Bryan
24 : 9 : 5
Total amount that Charlie, Adam and Bryan have
= 24 u + 9 u + 5 u
= 38 u
38 u = 418
1 u = 418 ÷ 38 = 11
Amount that Bryan has less than Charlie
= 24 u - 5 u
= 19 u
= 19 x 11
= $209
Answer(s): $209
