\(\dfrac{-4}{3}+\dfrac{1}{3}:\left(-1,5\right)=\dfrac{-4}{3}+\dfrac{-2}{9}=\dfrac{-14}{9}\)
\(=\dfrac{-4}{3}+\dfrac{1}{3}:\dfrac{-3}{2}=\dfrac{-4}{3}-\dfrac{2}{9}=\dfrac{-12-2}{9}=-\dfrac{14}{9}\)
\(\dfrac{-4}{3}+\dfrac{1}{3}:\left(\dfrac{-1}{5}\right)\)
\(=\dfrac{-4}{3}+\dfrac{1}{3}.\left(-5\right)\)
\(=\dfrac{-4}{3}+\dfrac{-5}{3}\)
\(=-3\)
