Answer 1

[T.Ps]

#)Giải :

Ta có : \(1-\frac{2010}{2011}=\frac{1}{2011}\)

            \(1-\frac{2011}{2012}=\frac{1}{2012}\)

Vì \(\frac{1}{2011}>\frac{1}{2012}\Rightarrow\frac{2010}{2011}>\frac{2011}{2012}\)

Answer 2

[nguyễn tuấn thảo]

\(\frac{2010}{2011}=1-\frac{1}{2011}\)

\(\frac{2011}{2012}=1-\frac{1}{2012}\)

\(2011\)<\(2012\)\(\Rightarrow\frac{1}{2011}\)>\(\frac{1}{2012}\)

\(\Rightarrow\frac{2010}{2011}\)<\(\frac{2011}{2012}\)
