If the fractions have a common (same) denominator, you simply subtract the numerators

Example 5/8 - 3/8 = 2/8 or 1/4

If the fractions have different denominators, you have to convert the fractions to ones that have the same denominator (the least common denominator) and then subtract.

Example 5/8 - 2/5 = 25/40 - 16/40 (multiply the first by 5/5 and the second by 8/8)

with the result 9/40. (check to see if the answer is reducible)
