Question

So sánh -385/386 và -578/579

Answer 1

\(1-\frac{385}{386}=\frac{1}{386}\)

\(1-\frac{578}{579}=\frac{1}{579}\)

Ta có: \(\frac{1}{386}>\frac{1}{579}\)

\(\Rightarrow1-\frac{578}{579}< 1-\frac{385}{386}\)

\(\Rightarrow-\frac{578}{579}< -\frac{385}{386}\)

Vậy \(-\frac{578}{579}< -\frac{385}{386}\)
