Question

so sánh P và Q

\(P=\frac{2014}{2015}+\frac{2015}{2016}+\frac{2016}{2017}\)

\(Q=\frac{2014+2015+2016}{2015+2016+2017}\)

 

Answer 1

Ta có : P = 2014/2015 + 2015/2016 + 2016/2017 < 2014/(2015+2016+2017) + 2015/(2015+2016+2017) + 2016/(2015+2016+2017) = Q

Suy ra : P < Q

Vậy P < Q.

Answer 2

Ta thấy:\(\frac{2014}{2015}+\frac{2015}{2016}+\frac{2016}{2017}\)>\(\frac{2014+2015+2016}{2015+2016+2017}\)
Vậy     :P>Q
