a) The average mass = #(14 "kg")/"N"#, with #"N"# being the number of fish.

b) The average mass is given as #3/4 "kg"#. We can calculate the number of fish by setting the two values for the average mass equal, then solve for #"N"#.

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

#"N"=14 "kg"##-:##(3"kg")/(4)#=

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

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