a. Ta có:
\(\frac{33}{34}=1-\frac{1}{34}\)
\(\frac{34}{35}=1-\frac{1}{35}\)
Do \(\frac{1}{34}>\frac{1}{35}\Rightarrow1-\frac{1}{34}< 1-\frac{1}{35}\)
\(\Leftrightarrow\frac{33}{34}< \frac{34}{35}\)
\(\Rightarrow\frac{-33}{34}>\frac{-34}{35}.\)
Ta có :
\(1-\frac{1}{34}=\frac{33}{34}\)
\(1-\frac{1}{35}=\frac{34}{35}\)
Do \(\frac{1}{34}>\frac{1}{35}\)
\(\Rightarrow1-\frac{1}{34}< 1-\frac{1}{35}\)
\(\Rightarrow\frac{33}{34}< \frac{34}{35}\)
\(\Rightarrow\frac{-33}{34}>-\frac{34}{35}\)
Vậy \(-\frac{33}{34}>-\frac{34}{35}\)
