Subtracting Fractions:
To subtract two or more fractions, first make all the fractions have the same denominator. To do this, find the least common multiple of the two denominators. The Least Common Multiple (LCM) is the smallest number that is a multiple of the two numbers. For example, the LCM of 6 and 8 is 24.

Once the denominators are the same, just subtract the numerators. Then simplify the answer (put the fraction in lowest terms).

Subtracting Fractions Worksheets:
 LCM, GCDFactor two numbers into primes, then use a Venn diagram to compute their Least Common Multiple (LCM) and Greatest Common Divisor (GCD). Or go to an example of how to use this diagram. Subtracting Fractions With the Same DenominatorsSubtract the fractions (they have the same denominators). Subtracting Fractions With Different DenominatorsSubtract the fractions (they have different denominators). Subtracting Fractions Word ProblemsSolve word problems that involve subtracting fractions.
