The common ratio when the fish population is decreasing by 2% will be 0.98
It is given that the fish population in the lake is decreasing by 2% every year.
Now to find the common ratio we will calculate next year's population
The next year's population will be given as
[tex]100-2=98[/tex]
Here the population of the fish will be 98% for the next year or we can convert it
98 % = [tex]\dfrac{98}{100} =0.98[/tex]
Thus the common ratio when the fish population is decreasing by 2% will be 0.98
