Multiplying Fractions

Question 1:

\frac{4}{15} \times \frac{3}{32}

\frac{{}^{1}4}{{}_{5}15} \times \frac{3^{1}}{32_{8}} = \frac{1}{40}

Question 2:

\frac{5}{6} \times \frac{18}{55}

\frac{{}^{1}5}{{}_{1}6} \times \frac{18^{3}}{55_{11}} = \frac{3}{11}

Question 3:

\frac{5}{28} \times \frac{8}{45}

\frac{{}^{1}5}{{}_{7}28} \times \frac{8^{2}}{45_{9}} = \frac{2}{63}

Question 4:

\frac{27}{56} \times \frac{40}{99}

\frac{{}^{3}27}{{}_{7}56} \times \frac{40^{5}}{99_{11}} = \frac{15}{77}
