\( 2\frac{2}{3} = \frac{2 \cdot 3 + 2}{3} = \frac{8}{3} \)
\( 5\frac{5}{6} = \frac{5 \cdot 6 + 5}{6} = \frac{35}{6} \)
\( \frac{2}{3} - \frac{1}{6} = \frac{2 \cdot 2}{3 \cdot 2} - \frac{1}{6} = \frac{4}{6} - \frac{1}{6} = \frac{3}{6} = \frac{1}{2} \)
\( \frac{1}{2} \cdot \frac{8}{3} = \frac{1 \cdot 8}{2 \cdot 3} = \frac{8}{6} = \frac{4}{3} \)
\( \frac{4}{3} : \frac{35}{6} = \frac{4}{3} \cdot \frac{6}{35} = \frac{4 \cdot 6}{3 \cdot 35} = \frac{24}{105} \)
\( \frac{24}{105} = \frac{8}{35} \)
Ответ: \(\frac{8}{35}\).
