Multiplying Mixed Numbers

Question 1:

10 \frac{1}{2} \times \frac{12}{35}

\frac{{}^{3}21}{{}_{1}2} \times \frac{12^{6}}{35_{5}} = \frac{18}{5} = 3 \frac{3}{5}

Question 2:

3 \frac{15}{16} \times \frac{8}{9}

\frac{{}^{7}63}{{}_{2}16} \times \frac{8^{1}}{9_{1}} = \frac{7}{2} = 3 \frac{1}{2}

Question 3:

6 \frac{3}{4} \times \frac{20}{63}

\frac{{}^{3}27}{{}_{1}4} \times \frac{20^{5}}{63_{7}} = \frac{15}{7} = 2 \frac{1}{7}

Question 4:

6 \frac{1}{4} \times \frac{4}{45}

\frac{{}^{5}25}{{}_{1}4} \times \frac{4^{1}}{45_{9}} = \frac{5}{9}
