<bot>: How many females are adults? ** 60% of female alligators are adults because 100 - 40 = <<100-40=60>>60
How many female alligators are there? ** There are 25 female alligators because 15 / .6 = <<15/.6=25>>25
How many alligators are there? ** There are 50 alligators in total because 25 / .5 = <<25/.5=50>>50
How many male alligators are there? ** There are 25 male alligators because 50 / 2 = <<50/2=25>>25
