Like the other worksheet sets, these dividing fractions worksheets come in varying levels of difficulty. There are problems that are designed to exercise your cross-cancelling skills, and the answer keys on these worksheets provide detailed breakdowns of how the cross-cancelling works for each problem. Other worksheets include problems with mixed fractions (whole values).
In the simplest cases, the two fractions will already have a common denominator. In this case, add the numerators and then reduce the resulting fraction.
