The ratio of Adam's money to Charlie's money is 5 : 3.
The ratio of Charlie's money to Bryan's money is 9 : 2.
The total amount that they have is $104.
How much less money does Bryan have than Adam?
Adam |
Charlie |
Bryan |
5 x 3 |
3 x 3 |
|
|
9 x 1 |
2 x 1 |
15 u |
9 u |
2 u |
Amount that Charlie has is the repeated identity.
Make the amount that Charlie has the same using the LCM of 3 and 9.
LCM of 3 and 9 = 9
Adam : Charlie : Bryan
15 : 9 : 2
Total amount that Adam, Charlie and Bryan have
= 15 u + 9 u + 2 u
= 26 u
26 u = 104
1 u = 104 ÷ 26 = 4
Amount that Bryan has less than Adam
= 15 u - 2 u
= 13 u
= 13 x 4
= $52
Answer(s): $52
