$A=\left(-0,5-\frac{2}{3}\right):\left(-3\right)+\left(-1,6\right):\left(-2\right)$

$A=\left(-\frac{1}{2}-\frac{2}{3}\right):\left(-\frac{3}{1}\right)+\left(-\frac{1}{6}\right):\left(-\frac{2}{1}\right)$

$A=\left(\frac{-3}{6}-\frac{4}{6}\right):\left(-\frac{3}{1}\right)+\left(-\frac{1}{6}\right).\left(-\frac{1}{2}\right)$

$A=\left(-\frac{7}{6}\right).\left(-\frac{1}{3}\right)+\frac{1}{12}$

$A=\frac{7}{18}+\frac{1}{12}$

$A=\frac{14}{36}+\frac{3}{36}$

$A=\frac{17}{36}$
