Question

So sánh: A và B biết: A=2017/2016+2018/2017,

B= 2017+2018/2016+2017

Mn ơi giúp mk với

Answer 1

Có: \(A>\frac{2016}{2016}+\frac{2017}{2017}=2\)

Có: \(B=\frac{4035}{4033}< 2\)

\(\Rightarrow A>B.\)

Answer 2

\(B=\frac{2017+2018}{2016+2017}=\frac{2017}{2016+2017}+\frac{2018}{2016+2017}\)

Ta có

\(\frac{2017}{2016+2017}< \frac{2017}{2016}\) ;

\(\frac{2018}{2017}< \frac{2018}{2017}\)

\(\Rightarrow B< \frac{2017}{2016}+\frac{2018}{2017}=A\)

Vậy B<A
