$\frac{2\frac{8}{9}}{1,3}:2=2\frac{8}{9}:1\frac{3}{10}:2=\frac{2\cdot9+8}{9}:\frac{1\cdot10+3}{10}\cdot\frac{1}{2}=\frac{18+8}{9}:\frac{10+3}{10}\cdot\frac{1}{2}=\\\\=\frac{26}{9}:\frac{13}{10}\cdot\frac{1}{2}=\frac{\not26^2}{9}\cdot\frac{\not10^5}{\not13_1}\cdot\frac{1}{\not2_1}=\frac{10}{9}=\boxed1\frac{\boxed1}{\boxed9}$
