tính

\(\dfrac{-5}{8}:\dfrac{15}{4}\) \(\dfrac{-15}{17}:\dfrac{25}{-34}\) \(-48:(\dfrac{-24}{5})\) \(\dfrac{-30}{7}:(\dfrac{-5}{-14})\)

\(\dfrac{15}{28}:(\dfrac{-9}{14})\) \(\dfrac{-7}{40}:(-\dfrac{21}{20})\) \((\dfrac{-4}{15}).(-\dfrac{-25}{8})\) \(\dfrac{5}{-14}.(-\dfrac{7}{10})\)

\(\dfrac{-15}{4}.(-\dfrac{16}{25})\) \(15.(-\dfrac{13}{10})\) \((-\dfrac{14}{5}).-10\) \((\dfrac{3}{-10}).(-\dfrac{-15}{2})\)
