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 steps for subtracting fractions is well illustrated in the fraction calculator at the link below. That page has a more detailed discussion of common denominators, mixed fractions and other topics that may help understand the steps necessary to subtract fractions.
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.
Reducing fractions is another skill involved in just about any of the fraction operations. The fraction worksheets on this page introduce reducing gradually by providing problems with increasingly more difficult denominators, and only gradually introducing mixed numbers and improper fractions.
