The ratio of Charlie's money to Bryan's money is 8 : 4.
The ratio of Bryan's money to Adam's money is 8 : 2.
The total amount that they have is $494.
How much less money does Adam have than Charlie?
Charlie |
Bryan |
Adam |
8 x 2 |
4 x 2 |

|
8 x 1 |
2 x 1 |
16 u |
8 u |
2 u |
Amount that Bryan has is the repeated identity.
Make the amount that Bryan has the same using the LCM of 4 and 8.
LCM of 4 and 8 = 8
Charlie : Bryan : Adam
16 : 8 : 2
Total amount that Charlie, Bryan and Adam have
= 16 u + 8 u + 2 u
= 26 u
26 u = 494
1 u = 494 ÷ 26 = 19
Amount that Adam has less than Charlie
= 16 u - 2 u
= 14 u
= 14 x 19
= $266
Answer(s): $266
