Пошаговое объяснение:

$\left(0,125-\frac{\frac{1}{18}+\frac{1}{8}}{\frac{1}{18}}\right):\left(\frac{2}{9}+\frac{\frac{7}{45}}{\frac{2}{15}-\frac{1}{18}}\right)+\frac{1}{2+\frac{6}{13}}+0,7^0=$

$=\left(\frac{1}{8}-\frac{\frac{4}{72}+\frac{9}{72}}{\frac{1}{18}}\right):\left(\frac{2}{9}+\frac{\frac{7}{45}}{\frac{12}{90}-\frac{5}{90}}\right)+\frac{1}{2\frac{6}{13}}+1=$

$=\left(\frac{1}{8}-\frac{\frac{13}{72}}{\frac{1}{18}}\right):\left(\frac{2}{9}+\frac{\frac{7}{45}}{\frac{7}{90}}\right)+\frac{1}{\frac{32}{13}}+1=$

$=\left(\frac{1}{8}-\frac{13}{72}:\frac{1}{18}\right):\left(\frac{2}{9}+\frac{7}{45}:\frac{7}{90}\right)+1:\frac{32}{13}+1=$

$=\left(\frac{1}{8}-\frac{13}{4}\right):\left(\frac{2}{9}+2\right)+\frac{13}{32}+1=$

$=\left(\frac{1}{8}-\frac{26}{8}\right):2\frac{2}{9}+1\frac{13}{32}=$

$=-\frac{25}{8}:\frac{20}{9}+1\frac{13}{32}=$

$=-\frac{25}{8}\cdot\frac{9}{20}+1\frac{13}{32}=$

$=-\frac{45}{32}+1\frac{13}{32}=$

$=-\frac{45}{32}+\frac{45}{32}=0$
