These dividing fractions worksheets have problems that can be solved with a cross multiply step, but they do not include wholes so do not require initially converting to improper fractions to solve.
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.
