    Division of Fractions

    All fractions should be in improper or proper form.

    Procedures:

    1. Take the reciprocal of the denominator or the divisor.
      The reciprocal of \( \frac{2}{3}\) is \( \frac{3}{2}\), the reciprocal of \( \frac{1}{5}\) is 5.
    2. Multiply the reciprocal to the numerator.

    Examples:

    1. Find the quotient of \( \frac{2}{3} \) ÷ \( \frac{5}{6}\)
    1. Reciprocal of the denominator \( \frac{5}{6} \) is \( \frac{6}{5}\)
    2. Multiply \( \frac{6}{5}\) to the numerator \( \frac{2}{3} \)
    3. \( \frac{6}{5}\) x \( \frac{2}{3} \) = \( \frac{12}{15} \)
    4. Simplify / Reduce
    5. \( \frac{12}{15} \) = \( \frac{4}{5}\)
    2. Find the quotient of \( \frac{8}{3} \) ÷ \( \frac{3}{5}\)
    1. Reciprocal of the denominator \( \frac{3}{5} \) is \( \frac{5}{3}\)
    2. Multiply \( \frac{5}{3}\) to the numerator \( \frac{8}{3} \)
    3. \( \frac{5}{3}\) x \( \frac{8}{3} \) = \( \frac{40}{9} \)
    4. Since the numerator and the denominator has no common factors \( \frac{40}{9}\) is the simplest form
