((-2 7/24:1 5/6-1 3/5*(-0,3))
—————————————
(-9,5:(5,7-4 12/35))​

Answer 1

$\frac{ - 2 \frac{7}{24} \div 1 \frac{5}{6} - 1 \frac{3}{5} \times ( - 0.3)}{ - 9.5 \div (5.7 - 4 \frac{12}{35} )} =0.11 \\ - 2 \frac{7}{24} \div 1 \frac{5}{6} = - \frac{55 \times 6}{24 \times 11} = - \frac{5}{4} = - 1 \frac{1}{4} \\ 1 \frac{3}{5} \times ( - 0.3) = - \frac{8 \times 3}{ 5\times 10} = - \frac{12}{25} \\ - 1 \frac{1}{4} - ( - \frac{12}{25} ) = - 1.25 + 0.48 = - 0.77 \\ 5.7 - 4 \frac{12}{35} = 5 \frac{7}{10} - 4 \frac{12}{35} = 5 \frac{49}{70} - 4 \frac{24}{70} = 1 \frac{25}{70} = 1 \frac{5}{14} \\ - 9.5 \div 1 \frac{5}{14} = - \frac{19 \times 14}{2 \times 19} = - 7 \\ - 0.77 \div ( - 7) = 0.11$
