Вычислим значение выражения:
$$\frac{29}{4} : 5 - \frac{4}{5} - \frac{3}{4} \cdot \left(3 - 1\frac{19}{30}\right) = \frac{29}{4} : 5 - \frac{4}{5} - \frac{3}{4} \cdot \left(\frac{90}{30} - \frac{49}{30}\right) = \frac{29}{4} : 5 - \frac{4}{5} - \frac{3}{4} \cdot \frac{41}{30} = \frac{29}{4} \cdot \frac{1}{5} - \frac{4}{5} - \frac{3}{4} \cdot \frac{41}{30} = \frac{29}{20} - \frac{4}{5} - \frac{123}{120} = \frac{29}{20} - \frac{4}{5} - \frac{41}{40} = \frac{29 \cdot 2}{20 \cdot 2} - \frac{4 \cdot 8}{5 \cdot 8} - \frac{41}{40} = \frac{58}{40} - \frac{32}{40} - \frac{41}{40} = \frac{58 - 32 - 41}{40} = \frac{26 - 41}{40} = \frac{-15}{40} = -\frac{3}{8}$$
Ответ: -3/8
