The ratio of Charlie's money to Adam's money is 8 : 5.
The ratio of Adam's money to Bryan's money is 3 : 1.
The total amount that they have is $440.
How much less money does Bryan have than Charlie?
Charlie |
Adam |
Bryan |
8 x 3 |
5 x 3 |

|
3 x 5 |
1 x 5 |
24 u |
15 u |
5 u |
Amount that Adam has is the repeated identity.
Make the amount that Adam has the same using the LCM of 5 and 3.
LCM of 5 and 3 = 15
Charlie : Adam : Bryan
24 : 15 : 5
Total amount that Charlie, Adam and Bryan have
= 24 u + 15 u + 5 u
= 44 u
44 u = 440
1 u = 440 ÷ 44 = 10
Amount that Bryan has less than Charlie
= 24 u - 5 u
= 19 u
= 19 x 10
= $190
Answer(s): $190
