If d : e = 4 : 3 and e : f = 7 : 8, then find d : e : f?
- 28 : 21 : 24
- 28 : 21 : 11
- 11 : 21 : 24
- None of these
Explanation
We are given:
d : e = 4 : 3
e : f = 7 : 8
To combine them, make the value of e the same in both ratios.
LCM of 3 and 7 = 21
So,
d : e = 4×7 : 3×7 = 28 : 21
e : f = 7×3 : 8×3 = 21 : 24
Now combine:
d : e : f = 28 : 21 : 24
