a) \(\frac{1}{2010}\)và \(\frac{-7}{19}\)
Ta có : \(\frac{1}{2010}>0>\frac{-7}{19}\)
\(\Rightarrow\frac{1}{2010}>\frac{-7}{19}\)
b)\(\frac{497}{-499}\)và \(\frac{-2345}{2341}\)
Ta có : \(\frac{497}{-499}< -1< \frac{-2345}{2341}\)
\(\Rightarrow\frac{497}{-499}>\frac{-2345}{2341}\)
c)\(\frac{2000}{2001}\)và \(\frac{2001}{2002}\)
Ta có : \(\frac{2000}{2001}=1-\frac{1}{2001};\frac{2001}{2002}=1-\frac{1}{2002}\)
mà \(\frac{1}{2001}>\frac{1}{2002}\Rightarrow1-\frac{1}{2001}< 1-\frac{1}{2002}\)
\(\Rightarrow\frac{2000}{2001}< \frac{2001}{2002}\)
