\(x=\frac{-25}{35}=\frac{-5}{7}\)
\(y=\frac{444}{-777}=\frac{111}{111}.\frac{-4}{7}\)
Vì \(\frac{-4}{7}>\frac{-5}{7}\Rightarrow\frac{111}{111}.\frac{-4}{7}>\frac{-5}{7}\Leftrightarrow x< y\)
1,X=−2535−2535=−57−57
Y=444−777444−777= −47−47
VÌ −47−47> −57−57
⇒X<Y
2,Y=110−50110−50= −115−115
X=−215−215
vì −215−215<−115−115
⇒y<x
