Subtract their numerators, and put on top of the common denominator. Thus, for example, 5/3 - 3/3 = 2/3.
Works for addition, too (add the numerators).

multiply the fractions until they have common denominators and then subtract them
Subtracting fractions is similar to adding fractions. If the fractions have the same denominator, you subtract the numerators. If the fractions have different denominators, you have to convert to a common denominator first.Subtracting fractions is similar to adding fractions.

Convert unlike fractions to equivalent fractions with common denominators by finding the LCM of the denominators.
by finding the common denominator of the fractions
If the denominators are the same, subtract the numerators. If the denominators are different, convert them to equivalent fractions with a common denominator and subtract the numerators.
