The ratio of Adam's money to Charlie's money is 8 : 2.
The ratio of Charlie's money to Bryan's money is 3 : 1.
The total amount that they have is $320.
How much less money does Bryan have than Adam?
Adam |
Charlie |
Bryan |
8 x 3 |
2 x 3 |

|
3 x 2 |
1 x 2 |
24 u |
6 u |
2 u |
Amount that Charlie has is the repeated identity.
Make the amount that Charlie has the same using the LCM of 2 and 3.
LCM of 2 and 3 = 6
Adam : Charlie : Bryan
24 : 6 : 2
Total amount that Adam, Charlie and Bryan have
= 24 u + 6 u + 2 u
= 32 u
32 u = 320
1 u = 320 ÷ 32 = 10
Amount that Bryan has less than Adam
= 24 u - 2 u
= 22 u
= 22 x 10
= $220
Answer(s): $220
