`B=(2015+2016+2017)/(2016+2017+2018)`

`=2015/(2016+2017+2018)+2016/(2016+2017+2018)+2017/(2016+2017+2018)`

Vì `2015/(2016+2017+2018)<2015/2016`

`2016/(2016+2017+2018)<2016/2017`

`2017/(2016+2017+2018)<2017/2018`

`=>B<A`

Bài 5

B= \(\dfrac{2015}{2016+2017+2018}\)+\(\dfrac{2016}{2016+2017+2018}\)+\(\dfrac{2017}{2016+2017+2018}\)

Ta có:\(\dfrac{2015}{2016}\)>\(\dfrac{2015}{2016+2017+2018}\),\(\dfrac{2016}{2017}\)>\(\dfrac{2016}{2016+2017+2018}\),\(\dfrac{2017}{2018}\)>\(\dfrac{2017}{2016+2017+2018}\)

⇒A>B
