Multiplying Mixed Numbers

Question 1:

7 \frac{1}{2} \times 1 \frac{3}{5}

\frac{{}^{3}15}{{}_{1}2} \times \frac{8^{4}}{5_{1}} = \frac{12}{1} = 12

Question 2:

4 \frac{3}{8} \times 4 \frac{4}{7}

\frac{{}^{5}35}{{}_{1}8} \times \frac{32^{4}}{7_{1}} = \frac{20}{1} = 20

Question 3:

4 \frac{1}{5} \times 1 \frac{17}{28}

\frac{{}^{3}21}{{}_{1}5} \times \frac{45^{9}}{28_{4}} = \frac{27}{4} = 6 \frac{3}{4}

Question 4:

3 \frac{3}{7} \times \frac{7}{12}

\frac{{}^{2}24}{{}_{1}7} \times \frac{7^{1}}{12_{1}} = \frac{2}{1} = 2
