Develop addition and subtraction skills with fractions

This worksheet presents a set of fraction problems of mixed addition and subtraction operations.

Difficulty increases with larger denominators, so use this metric to adjust the challenge of the addition problems. With large denominators, the task of getting both sides with the same denominator becomes much more difficult. You can also select to have both arguments to the problems have the same denominator, in which case the task is reduced to a simple addition or subtraction problem. For additio nproblems, you can control the incidence of results that go over the value of one, and for subtraction problems you can control the incidence of negative results.
