a) The average mass = (14 "kg")/"N", with $\text{N}$ being the number of fish.

b) The average mass is given as $\frac{3}{4} \text{kg}$. We can calculate the number of fish by setting the two values for the average mass equal, then solve for $\text{N}$.

$\left(3 \text{kg")/(4)=(14 "kg")/("N}\right)$=

$\text{N"=14 "kg}$$\div$$\frac{3 \text{kg}}{4}$=

"N"=14 "kg" * (4)/(3"kg")=

"N"=(56cancel("kg"))/(3cancel("kg")) = 18.67=19#fish
