When adding fractions without a common denominator, it is necessary to find a common denominator before adding the numerators. Find two equivalent fractions by determining the least common multiple of the two denominators and using that as the denominator for both fractions.
The worksheets on this page have various types of practice for multiplying fractions. Included are problems that focus on cross-cancelling which is a skill that greatly simplifies the process of reducing fractions in the answer step. Cross cancelling prior to multiplying fractions results in much smaller products which are significantly easier to reduce and turn into proper fractions.
