Division of Fractions
All fractions should be in
improper or proper form
.
Procedures:
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.
Multiply the reciprocal to the numerator.
Examples:
1. Find the quotient of
\( \frac{2}{3} \) ÷ \( \frac{5}{6}\)
Reciprocal of the denominator \( \frac{5}{6} \) is \( \frac{6}{5}\)
Multiply \( \frac{6}{5}\) to the numerator \( \frac{2}{3} \)
\( \frac{6}{5}\) x \( \frac{2}{3} \) = \( \frac{12}{15} \)
Simplify / Reduce
\( \frac{12}{15} \) = \( \frac{4}{5}\)
2. Find the quotient of
\( \frac{8}{3} \) ÷ \( \frac{3}{5}\)
Reciprocal of the denominator \( \frac{3}{5} \) is \( \frac{5}{3}\)
Multiply \( \frac{5}{3}\) to the numerator \( \frac{8}{3} \)
\( \frac{5}{3}\) x \( \frac{8}{3} \) = \( \frac{40}{9} \)
Since the numerator and the denominator has no common factors \( \frac{40}{9}\) is the simplest form
