No, Mike presented the ratio based on the change compared to the new amount. He ought to have utilized the ratio of the change against the original amount, which is represented as 55/275, or 20%.

Inessa [3926]
When the stretch is proportional to the weight, it can be expressed as:
weight/(49 cm) = (135 N)/(21 cm)
weight = (49/21)×135 N
weight = 315 N

The fish's weight would be 315 N.
