The ratio of Adam's money to Charlie's money is 5 : 1.
The ratio of Charlie's money to Bryan's money is 3 : 2.
The total amount that they have is $500.
How much less money does Bryan have than Adam?
Adam |
Charlie |
Bryan |
5 x 3 |
1 x 3 |

|
3 x 1 |
2 x 1 |
15 u |
3 u |
2 u |
Amount that Charlie has is the repeated identity.
Make the amount that Charlie has the same using the LCM of 1 and 3.
LCM of 1 and 3 = 3
Adam : Charlie : Bryan
15 : 3 : 2
Total amount that Adam, Charlie and Bryan have
= 15 u + 3 u + 2 u
= 20 u
20 u = 500
1 u = 500 ÷ 20 = 25
Amount that Bryan has less than Adam
= 15 u - 2 u
= 13 u
= 13 x 25
= $325
Answer(s): $325
