Ta có: \(\frac{a}{b}=\frac{a\left(b+2016\right)}{b\left(b+2016\right)}=\frac{ab+2016a}{b\left(b+2016\right)}\) ;
\(\frac{a+2016}{b+2016}=\frac{b\left(a+2016\right)}{b\left(b+2016\right)}=\frac{ab+2016b}{b\left(b+2016\right)}\)
Với a = b thì \(\frac{a}{b}=\frac{a+2016}{b+2016}\)
Với a < b thì \(\frac{a}{b}< \frac{a+2016}{b+2016}\)
Với a > b thì \(\frac{a}{b}>\frac{a+2016}{b+2016}\)
