Both multiplying and dividing fractions involve steps that can create large numbers that are often avoided by cross-cancelling. This is especially true when starting with mixed fractions that produce large numerators when they are turned into improper fractions for cross multiplication. Cross cancelling is a trick to pre-reduce the answer by removing a common factor from the numerator and denominator of the opposite fractions in the calculation. These dividing fractions worksheets have problems that create lots of opportunities for cross cancelling.
