Решение:
$\frac{-0,125 * 5}{(1\frac{28}{63} - \frac{17}{21}) * 7\frac{7}{8}} = \frac{-0,625}{(\frac{91}{63} - \frac{51}{63}) * \frac{63}{8}} = \frac{-0,625}{\frac{40}{63} * \frac{63}{8}} = \frac{-0,625}{5} = -0,125$
Ответ: −0,125

Решение:
$\frac{(\frac{21}{40} - \frac{19}{24}) * 0,7 + 0,04}{0,675 * 3,4 - 2,02} = \frac{\frac{63 - 95}{120} * \frac{7}{10} + 0,04}{0,675 * 3,4 - 2,02} = \frac{\frac{-14}{75} + \frac{4}{100}}{2,295 - 2,02} = \frac{\frac{-56 + 12}{300}}{0,275} = \frac{\frac{-44}{300}}{\frac{275}{1000}} = -\frac{44}{300} * \frac{1000}{275} = -\frac{44}{3} * \frac{10}{275} = -\frac{44}{3} * \frac{2}{55} = -\frac{88}{165} = -\frac{8}{15}$
Ответ: $-\frac{8}{15}$.

Решение:
$\frac{(13,25 - 2\frac{5}{27} - 10\frac{5}{6}) * 230,04 + 46,75}{(1\frac{3}{7} + 3\frac{1}{3}) : (12\frac{1}{3} - 14\frac{2}{7})} = \frac{(\frac{1325}{100} - \frac{59}{27} - \frac{65}{6}) * 230,04 + 46,75}{(\frac{10}{7} + \frac{10}{3}) : (\frac{37}{3} - \frac{100}{7})} = \frac{\frac{35775 - 5900 - 29250}{2700} * 230,04 + 46,75}{\frac{30 + 70}{21} : \frac{259 - 300}{21}} = \frac{\frac{625}{2700} * \frac{23004}{100} + \frac{4675}{100}}{\frac{100}{21} * \frac{-21}{41}} = \frac{\frac{213}{4} + \frac{4675}{100}}{\frac{-100}{41}} = \frac{\frac{5325 + 4675}{100}}{\frac{-100}{41}} = 100 * \frac{-41}{100} = -41$
Ответ: −41
