Answer 1

[Ác Mộng]

Ta có:\(1-\frac{2013}{2015}=\frac{2}{2015}\)

\(1-\frac{2011}{2013}=\frac{2}{2013}\)

Do \(\frac{2}{2015}\frac{2011}{2013}\)

Answer 2

[Yuan Bing Yan _ Viên Băng Nghiên]

\(\frac{2013}{2015}\)và\(\frac{2011}{2013}\)

=>\(\frac{2013}{2015}\)=\(\frac{4052169}{4056195}\)và\(\frac{2011}{2013}\)=\(\frac{4052165}{4056195}\)

Vì:\(\frac{4052169}{4056195}\)>\(\frac{4052165}{4056195}\)

Nên:\(\frac{2013}{2015}>\frac{2011}{2013}\)
