The ratio of Charlie's money to Bryan's money is 7 : 6.
The ratio of Bryan's money to Adam's money is 2 : 1.
The total amount that they have is $368.
How much more money does Charlie have than Adam?
Charlie |
Bryan |
Adam |
7 x 1 |
6 x 1 |
|
|
2 x 3 |
1 x 3 |
7 u |
6 u |
3 u |
Amount that Bryan has is the repeated identity.
Make the amount that Bryan has the same using the LCM of 6 and 2.
LCM of 6 and 2 = 6
Charlie : Bryan : Adam
7 : 6 : 3
Total amount that Charlie, Bryan and Adam have
= 7 u + 6 u + 3 u
= 16 u
16 u = 368
1 u = 368 ÷ 16 = 23
Amount that Charlie has more than Adam
= 7 u - 3 u
= 4 u
= 4 x 23
= $92
Answer(s): $92
