Multiplying Fractions

Question 1:

\frac{49}{96} \times \frac{16}{21}

\frac{{}^{7}49}{{}_{6}96} \times \frac{16^{1}}{21_{3}} = \frac{7}{18}

Question 2:

\frac{9}{32} \times \frac{40}{63}

\frac{{}^{1}9}{{}_{4}32} \times \frac{40^{5}}{63_{7}} = \frac{5}{28}

Question 3:

\frac{20}{27} \times \frac{9}{20}

\frac{{}^{1}20}{{}_{3}27} \times \frac{9^{1}}{20_{1}} = \frac{1}{3}

Question 4:

\frac{3}{14} \times \frac{7}{9}

\frac{{}^{1}3}{{}_{2}14} \times \frac{7^{1}}{9_{3}} = \frac{1}{6}
