Question 1:

\frac{21}{100} \div \frac{27}{40}

\frac{{}^{7}21}{{}_{5}100} \times \frac{40^{2}}{27_{9}} = \frac{14}{45}

Question 2:

\frac{5}{12} \div \frac{35}{36}

\frac{{}^{1}5}{{}_{1}12} \times \frac{36^{3}}{35_{7}} = \frac{3}{7}

Question 3:

\frac{21}{80} \div \frac{33}{50}

\frac{{}^{7}21}{{}_{8}80} \times \frac{50^{5}}{33_{11}} = \frac{35}{88}

Question 4:

\frac{3}{64} \div \frac{9}{16}

\frac{{}^{1}3}{{}_{4}64} \times \frac{16^{1}}{9_{3}} = \frac{1}{12}
