Có: \(\dfrac{-16}{10}=\dfrac{-16:2}{10:2}\dfrac{-8}{5}\)
\(\dfrac{25}{-13}=\dfrac{-25}{13}\)
MSC: 65
\(\dfrac{-8}{5}=\dfrac{-8.13}{5.13}=\dfrac{-104}{65}\)
\(\dfrac{-25}{13}=\dfrac{-25.5}{13.5}=\dfrac{-125}{65}\)
Có: -104 > -125 \(\Rightarrow\dfrac{-104}{65}>\dfrac{-125}{65}\) \(\Rightarrow\dfrac{-8}{5}>\dfrac{-25}{13}\)
hay \(\dfrac{-16}{10}>\dfrac{25}{-13}\)
Vậy .....
