I'm guessing you're using % for division. Not sure why.
when multiplying fractions, just multiply tops and bottoms, then simplify if necessary.
31/3 * 5/2 31*5 / 3*2 = 155/6
when dividing by a fraction, invert it and then multiply.
2/3%3/8 = 2/3 * 8/3 = 16/9
when adding fractions, find the common denominator, then just add the numerators.
8/9 - 5/6 = 16/18 - 15/18 = 1/18
thanks for the help oobleck
