Multiplying Fractions

Question 1:

\frac{5}{32} \times \frac{4}{25}

\frac{{}^{1}5}{{}_{8}32} \times \frac{4^{1}}{25_{5}} = \frac{1}{40}

Question 2:

\frac{9}{14} \times \frac{35}{99}

\frac{{}^{1}9}{{}_{2}14} \times \frac{35^{5}}{99_{11}} = \frac{5}{22}

Question 3:

\frac{4}{9} \times \frac{3}{32}

\frac{{}^{1}4}{{}_{3}9} \times \frac{3^{1}}{32_{8}} = \frac{1}{24}

Question 4:

\frac{10}{21} \times \frac{7}{15}

\frac{{}^{2}10}{{}_{3}21} \times \frac{7^{1}}{15_{3}} = \frac{2}{9}
