The ratio of Tommy's to Cole's money is 3 : 4. The ratio of Cole's to Henry's money is 3 : 4. If Tommy has $126, how much more does Henry have than Cole?
| Tommy |
Cole |
Henry |
| 3x3 |
4x3 |
|
| |
3x4 |
4x4 |
| 9 u |
12 u |
16 u |
The amount that Cole has is the repeated identity.
Use LCM to make it the same.
LCM of 4 and 3 = 12
Amount that Tommy has = 9 u
9 u = 126
1 u = 126 ÷ 9 = 14
Amount that Henry has more than Cole
= 16 u - 12 u
= 4 u
= 4 x 14
= $56
Answer(s): $56
