The ratio of Charlie's money to Bryan's money is 3 : 2.
The ratio of Bryan's money to Adam's money is 9 : 8.
The total amount that they have is $244.
How much more money does Charlie have than Adam?
Charlie |
Bryan |
Adam |
3 x 9 |
2 x 9 |
|
|
9 x 2 |
8 x 2 |
27 u |
18 u |
16 u |
Amount that Bryan has is the repeated identity.
Make the amount that Bryan has the same using the LCM of 2 and 9.
LCM of 2 and 9 = 18
Charlie : Bryan : Adam
27 : 18 : 16
Total amount that Charlie, Bryan and Adam have
= 27 u + 18 u + 16 u
= 61 u
61 u = 244
1 u = 244 ÷ 61 = 4
Amount that Charlie has more than Adam
= 27 u - 16 u
= 11 u
= 11 x 4
= $44
Answer(s): $44
