\(\frac{2016×2018+2}{2016×2017+2018}\)

Answer 1

\(\frac{2016\times2018+2}{2016\times2017+2018}=\frac{2016\times\left(2017+1\right)+2}{2016\times2017+2018}=\)\(=\frac{2016\times2017+2016+2}{2016\times2017+2018}=\frac{2016\times2017+2018}{2016\times2017+2018}=1\)

Answer 2

Ta có : \(\frac{2016\times2018+2}{2016\times2017+2018}=\frac{2016\left(2017+1\right)+2}{2016\times2017+2018}=\frac{2016\times2017+2016+2}{2016\times2017+2018}\)

\(=\frac{2016\times2017+2018}{2016\times2017+2018}=1\)

Answer 3

2016x(2016+2)+2016-2014  2016x2016+2x2016+2016-2014       2019 x 2016 - 2014    2019 x 2016 - 2016 + 2   2018 x 2016+2

_____________________ =____________________________= ________________=___________________=____________= 1

2016x(2016+1)+2016+2       2016 x 2016 + 1 x 2016 + 2016 + 2         2018 x 2016 + 2         2018 x 2016 +2         2018 x 2016 +2
