Dividing Mixed Numbers

Question 1:

1 \frac{17}{28} \div 1 \frac{7}{8}

\frac{{}^{3}45}{{}_{7}28} \times \frac{8^{2}}{15_{1}} = \frac{6}{7}

Question 2:

5 \frac{1}{4} \div 5 \frac{1}{4}

\frac{{}^{1}21}{{}_{1}4} \times \frac{4^{1}}{21_{1}} = \frac{1}{1} = 1

Question 3:

2 \frac{1}{3} \div 3 \frac{0}{1}

\frac{7}{3} \times \frac{1}{3} = \frac{7}{9}

Question 4:

2 \frac{3}{16} \div 2 \frac{11}{12}

\frac{{}^{1}35}{{}_{4}16} \times \frac{12^{3}}{35_{1}} = \frac{3}{4}
