a) \( \dfrac{-4}{13}:2=\dfrac{-4}{13.2}=\dfrac{-2.2}{13.2}=\dfrac{-2}{13};\)
b) \(24:\dfrac{-6}{11}=24.\dfrac{11}{-6}=24.\dfrac{-11}{6}=\dfrac{24.(-11)}{6}=\dfrac{4.6.(-11)}{6}=-44\)
c) \(\dfrac{9}{34}:\dfrac{3}{17}=\dfrac{9}{34}:\dfrac{17}{3}=\dfrac{9.17}{34.3}=\dfrac{3.3.17}{2.17.3}=\dfrac{3}{2}\)
