Answer 1

$\frac{2}{3} \div \frac{1}{12} = \frac{2}{3} \times \frac{12}{1} = 8$

$\frac{8}{9} \div \frac{9}{10} = \frac{8}{9} \times \frac{10}{9} = \frac{80}{81}$

$\frac{15}{22} \div \frac{5}{33} = \frac{15}{22} \times \frac{33}{5} = \frac{9}{2} = 4 \frac{1}{2}$

$4 \div \frac{2}{3} = 4 \times \frac{3}{2} = 6$

$3 \div 1 \frac{1}{2} = 3 \div \frac{3}{2} = 3 \times \frac{2}{3} = 2$

$1 \frac{1}{2} \div 2 \frac{1}{2} = \frac{3}{2} \div \frac{5}{2} = \frac{3}{2} \times \frac{2}{5} = \frac{3}{5}$

Answer 2

$\frac{2}{3} : \frac{1}{12} = \frac{2}{3} *\frac{12}{1} = \frac{2*12}{3*1} = \frac{24}{3} = 8.\\\\\frac{8}{9} : \frac{9}{10} = \frac{8*10}{9*9} = \frac{80}{81}.\\\\ \frac{15}{22} :\frac{5}{33} = \frac{15*33}{22*5} = \frac{5*3*11*3}{11*2*5} = \frac{9}{2} = 4\frac{1}{2} .\\\\4:\frac{2}{3} = \frac{4*3}{1*2} = \frac{12}{2} = 6.\\\\3:1\frac{1}{2} = 3:\frac{3}{2} = \frac{3*2}{1*3} = 2.\\\\1\frac{1}{2} :2\frac{1}{2} = \frac{3}{2} :\frac{5}{2} = \frac{3*2}{5*2}=\frac{3}{5}.$
