The ratio of Tim's to Neave's money is 4 : 7. The ratio of Neave's to Jenson's money is 4 : 5. If Tim has $176, how much more does Jenson have than Neave?
| Tim |
Neave |
Jenson |
| 4x4 |
7x4 |
|
| |
4x7 |
5x7 |
| 16 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 Tim has = 16 u
16 u = 176
1 u = 176 ÷ 16 = 11
Amount that Jenson has more than Neave
= 35 u - 28 u
= 7 u
= 7 x 11
= $77
Answer(s): $77
