To help my daughters learn fractions, I made an exercise generator. Now they hate me.

fraction_exercise_generator.py

#!/usr/bin/python3

from random import randrange, random
from fractions import Fraction
from functools import reduce
from operator import mul

def pf(f):
    '''Pretty print the fraction'''
    return "{}/{}".format(f.numerator,f.denominator)


while True:

    fractions = [Fraction( randrange(1,30), randrange(1,30) ) for i in range(randrange(2,6))]
    
    final = reduce(mul, fractions)
    
    if final.denominator <= 30:
        print("{} = {}".format(" x ".join([pf(f) for f in fractions]),pf(final)))
        input()
