Question

Suppose the total weight of the fish caught stayed the same but instead of 100 fish caught during the weeklong fishing trip only 10 fish were caught. How would the weight of each fish change?

Answer 1

The weight of each fish would be multiplied by 10.

Assume the first time, the weight was 800 lb.  Since there were 100 fish caught, the weight of each fish would be 800/100 = 8 lb.

This time, however, only 10 fish were caught.  The weight would be 800/10 = 80 lb.  

80 = 8(10), so the weight is 10 times more.
