    When subtracting fractions with unlike denominators, you must first find a common denominator by finding the least common multiple between the denominators.

  • 2

    To rename a fraction, multiply both the numerator and the denominator by the same number to get an equivalent fraction with the common denominator.

  • 3

    After subtracting the numerators, always check to see if the answer can be simplified by dividing the numerator and denominator by their greatest common factor.
