Question

SO SÁNH\(\frac{2016}{2017}\)+\(\frac{2017}{2018}\)VÀ \(\frac{2016+2017}{2017+2018}\)

Answer 1

Do : \(\frac{2016}{2017}>\frac{2016}{2017+2018}\)

        \(\frac{2017}{2018}>\frac{2017}{2017+2018}\)

\(\Rightarrow\frac{2016}{2017}+\frac{2017}{2018}>\frac{2016}{2017+2018}+\frac{2017}{2017+2018}=\frac{2016+2017}{2017+2018}\)

Vậy : \(\frac{2016}{2017}+\frac{2017}{2018}>\frac{2016+2017}{2017+2018}\)

      

Answer 2

Ta có:

\(\frac{2016}{2017}>\frac{2017}{2018}\Rightarrow A>\frac{2016}{2018}+\frac{2017}{2018}\Rightarrow A>\frac{2016+2017}{2018}\)

\(\frac{2016+2017}{2017+2018}=\frac{2016+2017}{4035}\)

Vì:\(\frac{2016+2017}{2018}>\frac{2016+2017}{4015}\)

Nên:\(\frac{2016}{2017}+\frac{2017}{2018}>\frac{2016+2017}{2017+2018}\)
