This can be done by identifying the least common multiple of the two denominators. After rewriting the fractions so they both have the common denominator, you can subtract the numerators as you would with any two fractions. video https://cdn.kastatic.org/googleusercontent/bXhENKEsU2-HJYbsZd2b6Ft3n_R060Q01MPUr3QKFY85ubU1Q6N5weJBzV4jJDcyXxXJtBUYZ3Z8wkbhdHitPcVN6Q Subtracting fractions with unlike denominators To subtract fractions with different denominators, you need to find a common denominator.
