Calculation with fractions

Once all questions are answered correctly, the image of an animal appears.
Fractions are entered in the form numerator/denominator (no space separated by a slash). If the result is an integer, it can be entered as is, e.g. 3 instead of 3/1.

Base of random numbers:

This page generates random fractions by generating a random numerator and denominator independently. In order to generate interesting numbers, numbers with many prime factors are generated as follows:
For each number in the above list "Base of random numbers", a coin is tossed and those numbers with head are selected. The random number is then the product of the selected numbers.
In order to obtain sufficiently many different numbers the above list should contain at least six numbers.

For an easy game, the numbers 2, 2, 2, 3, 3, 5, 5 are a possible choice.
For a harder game choose 2, 2, 2, 2, 3, 3, 5, 5, 7.
