The ratio of Vincent's to Cole's money is 8 : 7. The ratio of Cole's to Flynn's money is 3 : 5. If Vincent has $456, how much more does Flynn have than Cole?
Vincent |
Cole |
Flynn |
8x3 |
7x3 |
|
|
3x7 |
5x7 |
24 u |
21 u |
35 u |
The amount that Cole has is the repeated identity.
Use LCM to make it the same.
LCM of 7 and 3 = 21
Amount that Vincent has = 24 u
24 u = 456
1 u = 456 ÷ 24 = 19
Amount that Flynn has more than Cole
= 35 u - 21 u
= 14 u
= 14 x 19
= $266
Answer(s): $266
