The ratio of Charlie's money to Bryan's money is 8 : 1.
The ratio of Bryan's money to Adam's money is 3 : 1.
The total amount that they have is $364.
How much more money does Charlie have than Adam?
Charlie |
Bryan |

8 x 3 |
1 x 3 |

3 x 1 |
1 x 1 |
24 u |
3 u |
1 u |
Amount that Bryan has is the repeated identity.
Make the amount that Bryan has the same using the LCM of 1 and 3.
LCM of 1 and 3 = 3
Charlie : Bryan : Adam
24 : 3 : 1
Total amount that Charlie, Bryan and Adam have
= 24 u + 3 u + 1 u
= 28 u
28 u = 364
1 u = 364 ÷ 28 = 13
Amount that Charlie has more than Adam
= 24 u - 1 u
= 23 u
= 23 x 13
= $299
Answer(s): $299
