The ratio of Wesley's to Tim's money is 6 : 5. The ratio of Tim's to Jenson's money is 3 : 5. If Wesley has $306, how much less does Tim have than Jenson?
| Wesley |
Tim |
Jenson |
| 6x3 |
5x3 |
|
| |
3x5 |
5x5 |
| 18 u |
15 u |
25 u |
The amount that Tim has is the repeated identity.
Use LCM to make it the same.
LCM of 5 and 3 = 15
Amount that Wesley has = 18 u
18 u = 306
1 u = 306 ÷ 18 = 17
Amount that Tim has less than Jenson
= 25 u - 15 u
= 10 u
= 10 x 17
= $170
Answer(s): $170
