This problem can be solved by "trial and improvement" or as follows.
Let us assume that the calculator Kermit used has rounded of a recurring decimal. Let this number be x.
x = 1.090909....
100x = 109.090909.....
Subtract the first equation from the second
99x = 108
x = 108/99
x = 12/11
So the two numbers were 12 and 11 (or any multiples of them).

12 flies in 11 minutes!
