[tex]6:\frac{2}{5}=6\cdot\frac{5}{2}=3\cdot5=15\\\\6\frac{6}{8}:9=6\frac{3}{4}:9=\frac{27}{4}\cdot\frac{1}{9}=\frac{3}{4}[/tex]
[tex]6 : \frac{2}{5} = \frac{6}{1} * \frac{5}{2} = \frac{30}{2} = \boxed{15}[/tex]
[tex]6 \frac{6}{8} : 9 = \frac{54}{8} * \frac{1}{9} = \frac{54}{72} = \boxed{\frac{3}{4}}[/tex]
