Once students have a basic familiarity with fractions, the next step is to understand how to compare fractions. Sometimes the concept of denominators takes a little time to grasp. Often students will confuse a larger denominator with a larger value for the fraction, when in reality the numerator, not the denominator, expressed the actual value being represented. The size of the numerator relative to the denominator is what ultimately describes the actual value of the fraction.
Subtracting fractions is similar to adding fractions. Most of the work involves the denominator. If the denominators of the two fractions are already the same, much of the work is done. Simply subtract the two numerators to get the answer fraction using the same denominator, and then reduce and make a proper fraction.
If the answers numerator is greater than the denominator, then the answer is an improper fraction. This fraction should be turned into a proper fraction by taking wholes out of the numerator until the numerator is less than the denominator.
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.
