The ratio of Valen's to George's money is 8 : 9. The ratio of George's to Ethan's money is 4 : 5. If Valen has $544, how much less does George have than Ethan?
| Valen |
George |
Ethan |
| 8x4 |
9x4 |
|
| |
4x9 |
5x9 |
| 32 u |
36 u |
45 u |
The amount that George has is the repeated identity.
Use LCM to make it the same.
LCM of 9 and 4 = 36
Amount that Valen has = 32 u
32 u = 544
1 u = 544 ÷ 32 = 17
Amount that George has less than Ethan
= 45 u - 36 u
= 9 u
= 9 x 17
= $153
Answer(s): $153
