[tex]1\frac{2}{3} : 2\frac{1}{6} = \frac{5}{3} : \frac{13}{6} =\frac{5}{3} \cdot \frac{6}{13} =\frac{30}{39}[/tex]
b)
[tex]1\frac{3}{5} : 7\frac{1}{5} = \frac{8}{5} :\frac{36}{5} =\frac{8}{5} \cdot \frac{5}{36} =\frac{2}{9}[/tex]
c)
[tex]2\frac{4}{7} : 2\frac{1}{4} =\frac{18}{7} : \frac{9}{4} = \frac{18}{7} \cdot \frac{4}{9} =\frac{8}{7} = 1\frac{1}{7}[/tex]
d)
[tex]1\frac{3}{10} : 1\frac{1}{12} =\frac{13}{10} : \frac{13}{12} = \frac{13}{10} \cdot \frac{12}{13} =\frac{12}{10} = \frac{6}{5} = 1\frac{2}{5}[/tex]
