The ratio of Daniel's to Zane's money is 8 : 5. The ratio of Zane's to Albert's money is 3 : 4. If Daniel has $456, how much more does Albert have than Zane?
| Daniel |
Zane |
Albert |
| 8x3 |
5x3 |
|
| |
3x5 |
4x5 |
| 24 u |
15 u |
20 u |
The amount that Zane has is the repeated identity.
Use LCM to make it the same.
LCM of 5 and 3 = 15
Amount that Daniel has = 24 u
24 u = 456
1 u = 456 ÷ 24 = 19
Amount that Albert has more than Zane
= 20 u - 15 u
= 5 u
= 5 x 19
= $95
Answer(s): $95
