The ratio of Adam's money to Charlie's money is 8 : 4.
The ratio of Charlie's money to Bryan's money is 8 : 4.
The total amount that they have is $560.
How much less money does Bryan have than Adam?
Adam |
Charlie |
Bryan |
8 x 2 |
4 x 2 |
|
|
8 x 1 |
4 x 1 |
16 u |
8 u |
4 u |
Amount that Charlie has is the repeated identity.
Make the amount that Charlie has the same using the LCM of 4 and 8.
LCM of 4 and 8 = 8
Adam : Charlie : Bryan
16 : 8 : 4
Total amount that Adam, Charlie and Bryan have
= 16 u + 8 u + 4 u
= 28 u
28 u = 560
1 u = 560 ÷ 28 = 20
Amount that Bryan has less than Adam
= 16 u - 4 u
= 12 u
= 12 x 20
= $240
Answer(s): $240
