Multiplying Mixed Numbers

Question 1:

2 \frac{1}{40} \times \frac{20}{63}

\frac{{}^{9}81}{{}_{2}40} \times \frac{20^{1}}{63_{7}} = \frac{9}{14}

Question 2:

2 \frac{6}{25} \times 4 \frac{2}{7}

\frac{{}^{8}56}{{}_{5}25} \times \frac{30^{6}}{7_{1}} = \frac{48}{5} = 9 \frac{3}{5}

Question 3:

6 \frac{2}{3} \times 1 \frac{1}{20}

\frac{{}^{1}20}{{}_{1}3} \times \frac{21^{7}}{20_{1}} = \frac{7}{1} = 7

Question 4:

2 \frac{1}{4} \times \frac{8}{15}

\frac{{}^{3}9}{{}_{1}4} \times \frac{8^{2}}{15_{5}} = \frac{6}{5} = 1 \frac{1}{5}
