Question 1:

\frac{8}{21} \div \frac{48}{77}

\frac{{}^{1}8}{{}_{3}21} \times \frac{77^{11}}{48_{6}} = \frac{11}{18}

Question 2:

\frac{32}{81} \div \frac{8}{9}

\frac{{}^{4}32}{{}_{9}81} \times \frac{9^{1}}{8_{1}} = \frac{4}{9}

Question 3:

\frac{9}{49} \div \frac{18}{35}

\frac{{}^{1}9}{{}_{7}49} \times \frac{35^{5}}{18_{2}} = \frac{5}{14}

Question 4:

\frac{4}{21} \div \frac{24}{49}

\frac{{}^{1}4}{{}_{3}21} \times \frac{49^{7}}{24_{6}} = \frac{7}{18}
