Dividing Mixed Numbers

Question 1:

2 \frac{2}{9} \div 1 \frac{4}{21}

\frac{{}^{4}20}{{}_{3}9} \times \frac{21^{7}}{25_{5}} = \frac{28}{15} = 1 \frac{13}{15}

Question 2:

6 \frac{3}{4} \div \frac{9}{20}

\frac{{}^{3}27}{{}_{1}4} \times \frac{20^{5}}{9_{1}} = \frac{15}{1} = 15

Question 3:

8 \frac{2}{5} \div 3 \frac{11}{15}

\frac{{}^{3}42}{{}_{1}5} \times \frac{15^{3}}{56_{4}} = \frac{9}{4} = 2 \frac{1}{4}

Question 4:

8 \frac{3}{4} \div \frac{21}{32}

\frac{{}^{5}35}{{}_{1}4} \times \frac{32^{8}}{21_{3}} = \frac{40}{3} = 13 \frac{1}{3}
