\(\left(-1\dfrac{2}{3}\right):\left(1\dfrac{1}{9}\right)+\dfrac{5}{9}\cdot\left(-2\dfrac{7}{10}\right):\left|2\dfrac{4}{7}\right|-\dfrac{2}{5}\cdot\left(\dfrac{5}{6}-\dfrac{1}{3}\right)\)
\(=-\dfrac{5}{3}:\dfrac{10}{9}+\dfrac{5}{9}\cdot\left(-\dfrac{27}{10}\right):\left(-\dfrac{18}{7}\right)-\dfrac{2}{5}\cdot\dfrac{1}{2}\)
\(=-\dfrac{3}{2}+\dfrac{7}{12}-\dfrac{1}{5}=-\dfrac{67}{60}\)
