The ratio of Bryan's money to Charlie's money is 6 : 5.
The ratio of Charlie's money to Adam's money is 2 : 1.
The total amount that they have is $243.
How much more money does Bryan have than Adam?
Bryan |
Charlie |
Adam |
6 x 2 |
5 x 2 |
|
|
2 x 5 |
1 x 5 |
12 u |
10 u |
5 u |
Amount that Charlie has is the repeated identity.
Make the amount that Charlie has the same using the LCM of 5 and 2.
LCM of 5 and 2 = 10
Bryan : Charlie : Adam
12 : 10 : 5
Total amount that Bryan, Charlie and Adam have
= 12 u + 10 u + 5 u
= 27 u
27 u = 243
1 u = 243 ÷ 27 = 9
Amount that Bryan has more than Adam
= 12 u - 5 u
= 7 u
= 7 x 9
= $63
Answer(s): $63
