Answer: 8 : 21
Step-by-step explanation:
A : B = 2 : 3 .....(i)
B : C = 4 : 7 .....(ii)
Multiply eq.(i) by '4' && eq.(ii) by '3'
A : B = 2*4 : 3*4 = 8:12
B : C = 4*3 : 7*3 = 12:21
[To make the value of 'B' same we multiplied accordingly]
A:C = 8:21

A/B=2×4/3×4=8/12
B/C=4×3/7×4=12/21
Therefore,A:C=8:21
B/C=4×3/7×4=12/21
Therefore,A:C=8:21

why we multiply by 4
We multiplied by '4' so that the value of 'B' in the first ratio becomes equal to value of 'B' in second ratio (here it was multiplied by 3).
ya got it thanks
