$1)4 \frac{1}{2} \div 2 \frac{1}{4} = \frac{9}{2} \times \frac{4}{9} = 2 \\ 2)2 \frac{4}{5} \div 1 \frac{2}{5} = \frac{14}{5} \times \frac{5}{7} = 2 \\ 3) \frac{7}{9} \div 2 \frac{1}{3} = \frac{7}{9} \times \frac{3}{7} = \frac{1}{3} \\ 4)8 \frac{1}{2} \div \frac{19}{20} = \frac{17}{2} \times \frac{20}{19} = 17 \times \frac{10}{19} = \frac{17 \times 10}{1 \times 19} = \frac{170}{19} = 8 \frac{18}{19}$
