Multiplying Mixed Numbers

Question 1:

2 \frac{1}{4} \times 1 \frac{1}{9}

\frac{{}^{1}9}{{}_{2}4} \times \frac{10^{5}}{9_{1}} = \frac{5}{2} = 2 \frac{1}{2}

Question 2:

1 \frac{1}{5} \times \frac{5}{9}

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

Question 3:

2 \frac{11}{12} \times \frac{14}{45}

\frac{{}^{7}35}{{}_{6}12} \times \frac{14^{7}}{45_{9}} = \frac{49}{54}

Question 4:

1 \frac{19}{21} \times \frac{18}{25}

\frac{{}^{8}40}{{}_{7}21} \times \frac{18^{6}}{25_{5}} = \frac{48}{35} = 1 \frac{13}{35}
