5. To subtract fractions that have a common denominator
Find a suitable common denominator for the fractions - Expand the fractions to have the common denominator and Subtract the fractions.

Fractions can be added only when they have the same denominator. When they do not - you must adjust them so that the denominators are the same.
Subtract the numerators to get the numerator of the difference. Assign the common denominator to the difference. Reduce or simplify the result as necessary.
