The ratio of Adam's money to Charlie's money is 9 : 1.
The ratio of Charlie's money to Bryan's money is 5 : 4.
The total amount that they have is $324.
How much less money does Bryan have than Adam?
Adam |
Charlie |
Bryan |
9 x 5 |
1 x 5 |

5 x 1 |
4 x 1 |
45 u |
5 u |
4 u |
Amount that Charlie has is the repeated identity.
Make the amount that Charlie has the same using the LCM of 1 and 5.
LCM of 1 and 5 = 5
Adam : Charlie : Bryan
45 : 5 : 4
Total amount that Adam, Charlie and Bryan have
= 45 u + 5 u + 4 u
= 54 u
54 u = 324
1 u = 324 ÷ 54 = 6
Amount that Bryan has less than Adam
= 45 u - 4 u
= 41 u
= 41 x 6
= $246
Answer(s): $246
