The ratio of Adam's money to Charlie's money is 6 : 4.
The ratio of Charlie's money to Bryan's money is 6 : 3.
The total amount that they have is $360.
How much less money does Bryan have than Adam?
Adam |
Charlie |
Bryan |
6 x 3 |
4 x 3 |
|
|
6 x 2 |
3 x 2 |
18 u |
12 u |
6 u |
Amount that Charlie has is the repeated identity.
Make the amount that Charlie has the same using the LCM of 4 and 6.
LCM of 4 and 6 = 12
Adam : Charlie : Bryan
18 : 12 : 6
Total amount that Adam, Charlie and Bryan have
= 18 u + 12 u + 6 u
= 36 u
36 u = 360
1 u = 360 ÷ 36 = 10
Amount that Bryan has less than Adam
= 18 u - 6 u
= 12 u
= 12 x 10
= $120
Answer(s): $120
