\frac{50}{99} \div \frac{20}{27}

\frac{{}^{5}50}{{}_{11}99} \times \frac{27^{3}}{20_{2}} = \frac{15}{22}

Question 2:

\frac{4}{77} \div \frac{20}{21}

\frac{{}^{1}4}{{}_{11}77} \times \frac{21^{3}}{20_{5}} = \frac{3}{55}

Question 3:

\frac{20}{63} \div \frac{60}{77}

\frac{{}^{1}20}{{}_{9}63} \times \frac{77^{11}}{60_{3}} = \frac{11}{27}

Question 4:

\frac{6}{25} \div \frac{18}{25}

\frac{{}^{1}6}{{}_{1}25} \times \frac{25^{1}}{18_{3}} = \frac{1}{3}
