\frac{2}{4} x \frac{1}{3} = \frac{1.2}{2.2} = \frac{1}{2} = \frac{1}{2} x \frac{1}{3}=\frac{1.1}{2.3}  = \frac{1}{6}

\frac{7}{10} x \frac{2}{3}  = \frac{7.2}{10.3} =\frac{14}{30} = \frac{7.2}{15.2} = \frac{7}{15}

\frac{2}{3} x \frac{1}{2} = \frac{2.1}{3.2} = \frac{2}{6} = \frac{1.2}{3.2} = \frac{1}{3}

\frac{6}{7} x \frac{1}{5} = \frac{6.1}{7.5} = \frac{6}{35}

\frac{3}{7} x \frac{1}{6} = \frac{3.1}{7.6}=\frac{3}{42}  = \frac{1.3}{14.3} = \frac{1}{14}

\frac{2}{6}:\frac{3}{10} = \frac{1}{3} x \frac{10}{9}  = \frac{10}{9} = \frac{1.9+1}{9} = \frac{1.9}{9}  +\frac{1}{9} = 1 \frac{1}{9}

\frac{2}{4}:\frac{1}{5} =\frac{1.2}{2.2}:\frac{1}{5}=\frac{1}{2}:\frac{1}{5}=\frac{1}{2} x\frac{5}{1}  =\frac{1.5}{2.1} =\frac{5}{2}=\frac{2.2+1}{2}=2\frac{1}{2}

\frac{4}{6} :\frac{1}{2}= \frac{2.2}{3.2}:\frac{1}{2} =\frac{2}{3}:\frac{1}{2} =\frac{2}{3}x\frac{2}{1} =\frac{2.2}{3.1}=\frac{4}{3}=\frac{1.3+1}{3}=1\frac{1}{3}

\frac{1}{2} :\frac{3}{7}=\frac{1}{2} x\frac{7}{3} =\frac{1.7}{2.3} =\frac{7}{6}=\frac{1.6+1}{6}=1\frac{1}{6}

\frac{1}{3}:\frac{2}{9}=\frac{1}{3} x\frac{9}{2}  =\frac{1.9}{3.2}=\frac{9}{6}=\frac{3.3}{2.3}=\frac{3}{2} =\frac{1.2+1}{2}=1\frac{1}{2}

\frac{3}{10} :\frac{1}{6} =\frac{3}{10} x\frac{6}{1} =\frac{3.6}{10.1} =\frac{18}{10} =\frac{9}{5} =\frac{1.5+4}{5} =1\frac{4}{5}
