Many of the answers to these exercises require UNSIMPLIFIED fractions as answers in order to be counted correct. This is in spite of the fact that the "acceptable answers" sidebar always requires **simplified** fractions in order to qualify as a correct answer. The random generation of exercise questions means it can take a while for the pattern to be apparent, and frustrating to see the coloured progress bar keep dropping back down.
NOTE: Khan Academy still has the best interactive study programs anywhere. Many thanks.
