\frac{25}{72} \div \frac{55}{63}

\frac{{}^{5}25}{{}_{8}72} \times \frac{63^{7}}{55_{11}} = \frac{35}{88}

Question 2:

\frac{3}{14} \div \frac{9}{14}

\frac{{}^{1}3}{{}_{1}14} \times \frac{14^{1}}{9_{3}} = \frac{1}{3}

Question 3:

\frac{12}{77} \div \frac{6}{7}

\frac{{}^{2}12}{{}_{11}77} \times \frac{7^{1}}{6_{1}} = \frac{2}{11}

Question 4:

\frac{3}{20} \div \frac{21}{40}

\frac{{}^{1}3}{{}_{1}20} \times \frac{40^{2}}{21_{7}} = \frac{2}{7}
