Question

so sánh \(\frac{20132013}{20152015}\)và \(\frac{20152015}{20172017}\)

Answer 1

\(\frac{20132013}{20152015}=\frac{20132013:10001}{20152015:10001}=\frac{2013}{2015}=1-\frac{2}{2015}\)

\(\frac{20152015}{20172017}=\frac{20152015:10001}{20172017:10001}=\frac{2015}{2017}=1-\frac{1}{2017}\)

\(1-\frac{1}{2015}

Answer 2

ta có : \(\frac{20152015}{20172017}=\frac{2015}{2017}\)

\(\frac{20132013}{20152015}=1-\frac{20132013}{20152015}=\frac{2}{20152015}\)

\(\frac{2015}{2017}=1-\frac{2015}{2017}=\frac{2}{2017}\)

mà \(\frac{2}{2017}>\frac{2}{20152015}\) nên \(\frac{20152015}{20172017}
