Question

So sánh A = \(\frac{2015}{-2014}\)  và  B = \(\frac{2016}{-2015}\)ta được   A   B

Answer 1

\(\frac{2015}{2014}-1=\frac{1}{2014}>\frac{1}{2015}=\frac{2016}{2015}-1\Rightarrow\frac{2015}{2014}>\frac{2016}{2015}\Rightarrow-\frac{2015}{2014}

Answer 2

\(1+A=1+\frac{2015}{-2014}=\frac{-1}{2014}\)

\(1+B=1+\frac{2016}{-2015}=\frac{-1}{2015}\)

Vì \(\frac{-1}{2014}
