Question

3a=5b and 2b=7c then find the a:b:c.
ANY OTHER WAY?? ​

Answer 1

Yes your answer is correct.

Answer 2

Simpler way to solve is to 'connect' equality.

We know that a:b=5:3 & b:c=7:2

Connecting means that a:b and b:c becomes 35:21 and 21:6

The ratio becomes a:b:c=35:21:6

This method is definitely easier.
