The ratio of Charlie's money to Adam's money is 9 : 1.
The ratio of Adam's money to Bryan's money is 5 : 2.
The total amount that they have is $260.
How much more money does Charlie have than Bryan?
Charlie |
Adam |
Bryan |
9 x 5 |
1 x 5 |

5 x 1 |
2 x 1 |
45 u |
5 u |
2 u |
Amount that Adam has is the repeated identity.
Make the amount that Adam has the same using the LCM of 1 and 5.
LCM of 1 and 5 = 5
Charlie : Adam : Bryan
45 : 5 : 2
Total amount that Charlie, Adam and Bryan have
= 45 u + 5 u + 2 u
= 52 u
52 u = 260
1 u = 260 ÷ 52 = 5
Amount that Charlie has more than Bryan
= 45 u - 2 u
= 43 u
= 43 x 5
= $215
Answer(s): $215
