Vì \(\frac{2019}{2020}=1-\frac{2019}{2020}=\frac{1}{2020}\)
\(\frac{2006}{2007}=1-\frac{2006}{2007}=\frac{1}{2007}\)
Vì \(\frac{1}{2020}< \frac{1}{2007}=>\frac{2019}{2020}>\frac{2006}{2007}\)
Vậy\(\frac{2019}{2020}>\frac{2006}{2007}\)
Chiều nay mình giải tiếp cho.
Ta có \(\frac{33}{-37}=\frac{-33}{37}\)
Mà \(\frac{-33}{37}>\frac{-34}{37}>\frac{-34}{35}\)=>\(\frac{-33}{37}>\frac{-34}{35}\)
Vậy \(\frac{33}{-37}>\frac{-34}{35}\)
