Multiplying Fractions

Question 1:

\frac{7}{8} \times \frac{4}{35}

\frac{{}^{1}7}{{}_{2}8} \times \frac{4^{1}}{35_{5}} = \frac{1}{10}

Question 2:

\frac{9}{20} \times \frac{50}{63}

\frac{{}^{1}9}{{}_{2}20} \times \frac{50^{5}}{63_{7}} = \frac{5}{14}

Question 3:

\frac{9}{14} \times \frac{7}{27}

\frac{{}^{1}9}{{}_{2}14} \times \frac{7^{1}}{27_{3}} = \frac{1}{6}

Question 4:

\frac{3}{8} \times \frac{8}{33}

\frac{{}^{1}3}{{}_{1}8} \times \frac{8^{1}}{33_{11}} = \frac{1}{11}
