Question

A:B=1/2:1/3 and B:C=1/4:1/5​​

Answer 1

Answer:

A:B=1/4×5/1=5/4

B:C=1/7×6/1=6/7

Here the LCM of B terms 4 and 6 is 12

Now making terms of B as 12

A/B=(5×3)/(4×3)=15/12=15:12

B/C=(6×2)/(7×2)=12/14=12:14

So A:B:C=15:12:14

(ii) It is given that

3A=4B

We can write it as

A/B=4/3

A:B=4:3

Similarly 4B=6C

We can write it as

B/C=6/4=3/2

B:C=3:2

So we get

A:B:C=4:3:2
