This fraction worksheet is great for working on multiplying fractions with Cross Cancelling. The problems may be selected for four different degrees of difficulty. The easiest will keep the denominators 2, 3, 4, 5, & 10 and the numerators between 1 and 9. The hardest will keep the denominators 2 thru 30 and the numerators between 1 and 29. The answer worksheet will show the progression on how to solve the problems including the cross cancelling. First rewrite the problem, and then do the cross cancelling and reduce, next multiply the numerators and then the denominators. This fraction worksheet will generate 10 or 15 fraction multiplication problems per worksheet and show the cross cancelling required to solve the problem.
