Multiplying Fractions

Question 1:

\frac{8}{35} \times \frac{7}{32}

\frac{{}^{1}8}{{}_{5}35} \times \frac{7^{1}}{32_{4}} = \frac{1}{20}

Question 2:

\frac{25}{42} \times \frac{7}{25}

\frac{{}^{1}25}{{}_{6}42} \times \frac{7^{1}}{25_{1}} = \frac{1}{6}

Question 3:

\frac{9}{32} \times \frac{80}{99}

\frac{{}^{1}9}{{}_{2}32} \times \frac{80^{5}}{99_{11}} = \frac{5}{22}

Question 4:

\frac{9}{10} \times \frac{10}{81}

\frac{{}^{1}9}{{}_{1}10} \times \frac{10^{1}}{81_{9}} = \frac{1}{9}
