Multiplying Fractions

Question 1:

\frac{32}{63} \times \frac{7}{8}

\frac{{}^{4}32}{{}_{9}63} \times \frac{7^{1}}{8_{1}} = \frac{4}{9}

Question 2:

\frac{30}{77} \times \frac{7}{15}

\frac{{}^{2}30}{{}_{11}77} \times \frac{7^{1}}{15_{1}} = \frac{2}{11}

Question 3:

\frac{7}{81} \times \frac{45}{77}

\frac{{}^{1}7}{{}_{9}81} \times \frac{45^{5}}{77_{11}} = \frac{5}{99}

Question 4:

\frac{4}{21} \times \frac{3}{8}

\frac{{}^{1}4}{{}_{7}21} \times \frac{3^{1}}{8_{2}} = \frac{1}{14}
