Multiplying Fractions

Question 1:

\frac{7}{10} \times \frac{25}{77}

\frac{{}^{1}7}{{}_{2}10} \times \frac{25^{5}}{77_{11}} = \frac{5}{22}

Question 2:

\frac{63}{100} \times \frac{10}{27}

\frac{{}^{7}63}{{}_{10}100} \times \frac{10^{1}}{27_{3}} = \frac{7}{30}

Question 3:

\frac{16}{33} \times \frac{3}{8}

\frac{{}^{2}16}{{}_{11}33} \times \frac{3^{1}}{8_{1}} = \frac{2}{11}

Question 4:

\frac{8}{15} \times \frac{15}{28}

\frac{{}^{2}8}{{}_{1}15} \times \frac{15^{1}}{28_{7}} = \frac{2}{7}
