The probability of getting a female fish is 30%. If there are 18 female fish in the tank, how many total fish are in the tank?

I need to know how to do i for other equations, and what this answer is.

Let total number of fish be T. Then 0.3*T = 18 so T = 18/0.3 or T = 60

Nevermind I found out how to do it.

18 = 30

x 100

cross multiply

30x=1,800

x=60

Whoops started before you sent...

Thanks anyway.
