A project that uses my simplifying script to good use. It has a 'Quiz' and 'Type in' mode. In 'Type in', you type in the numerator and denominator of your fraction and the project will give you the simplified answer. In 'Quiz' mode, the project will give you 15 random simplifying questions for you to practise.
~To change modes, press the green flag and select again. ~My friend made up the title! ~Works with improper fractions too, but not with mixed numbers. ~If you get 'Infinity' or 'NaN' in your answer, it means you have entered an invalid or overlarge number.
