Question

so sánh \(\frac{2019}{2020}\)+\(\frac{2020}{2019}\)và\(\frac{444443}{222222}\)

Answer 1

\(\frac{2019}{2020}+\frac{2020}{2019}=1-\frac{1}{2020}+1+\frac{1}{2019}\)

\(=2+\frac{1}{2019}-\frac{1}{2020}\)

Vì \(\frac{1}{2019}>\frac{1}{2020}\Rightarrow\frac{1}{2019}-\frac{1}{2020}>0\)

\(\Rightarrow2+\frac{1}{2019}-\frac{1}{2020}>2\)

\(\frac{444443}{222222}=\frac{444444}{222222}-\frac{1}{222222}=2-\frac{1}{222222}< 2\)

\(\Rightarrow\frac{2019}{2020}+\frac{2020}{2019}>\frac{444443}{222222}\)
