Question 1:

\frac{8}{21} \div \frac{44}{63}

\frac{{}^{2}8}{{}_{1}21} \times \frac{63^{3}}{44_{11}} = \frac{6}{11}

Question 2:

\frac{10}{49} \div \frac{50}{63}

\frac{{}^{1}10}{{}_{7}49} \times \frac{63^{9}}{50_{5}} = \frac{9}{35}

Question 3:

\frac{2}{15} \div \frac{12}{25}

\frac{{}^{1}2}{{}_{3}15} \times \frac{25^{5}}{12_{6}} = \frac{5}{18}

Question 4:

\frac{7}{72} \div \frac{49}{54}

\frac{{}^{1}7}{{}_{4}72} \times \frac{54^{3}}{49_{7}} = \frac{3}{28}
