The ratio of Warren's to Neave's money is 6 : 7. The ratio of Neave's to Perry's money is 4 : 5. If Warren has $432, how much less does Neave have than Perry?
Warren |
Neave |
Perry |
6x4 |
7x4 |
|
|
4x7 |
5x7 |
24 u |
28 u |
35 u |
The amount that Neave has is the repeated identity.
Use LCM to make it the same.
LCM of 7 and 4 = 28
Amount that Warren has = 24 u
24 u = 432
1 u = 432 ÷ 24 = 18
Amount that Neave has less than Perry
= 35 u - 28 u
= 7 u
= 7 x 18
= $126
Answer(s): $126
