Question 2:

\frac{15}{56} \div \frac{33}{64}

\frac{{}^{5}15}{{}_{7}56} \times \frac{64^{8}}{33_{11}} = \frac{40}{77}

Question 3:

\frac{10}{49} \div \frac{4}{7}

\frac{{}^{5}10}{{}_{7}49} \times \frac{7^{1}}{4_{2}} = \frac{5}{14}

Question 4:

\frac{12}{35} \div \frac{32}{35}

\frac{{}^{3}12}{{}_{1}35} \times \frac{35^{1}}{32_{8}} = \frac{3}{8}
