$$ (8 - 2\frac{11}{12}) \cdot \frac{7}{16} : \frac{2}{27} = (8 - \frac{35}{12}) \cdot \frac{7}{16} : \frac{2}{27} = (\frac{96}{12} - \frac{35}{12}) \cdot \frac{7}{16} : \frac{2}{27} = \frac{61}{12} \cdot \frac{7}{16} : \frac{2}{27} = \frac{61}{12} \cdot \frac{7}{16} \cdot \frac{27}{2} = \frac{61 \cdot 7 \cdot 27}{12 \cdot 16 \cdot 2} = \frac{61 \cdot 7 \cdot 9}{4 \cdot 16 \cdot 2} = \frac{3843}{128} $$ $$ \frac{3843}{128} = 30 \frac{3}{128} $$Ответ: $$30 \frac{3}{128}$$
