Tính tỉ số \(\frac{A}{B}\)biết:
A=\(\frac{1}{2}\)+|\(\frac{-1}{3}\)|+\(\frac{1}{4}\)+....+|\(\frac{-1}{2015}\)|+\(\frac{1}{2016}\)+|\(\frac{-1}{2017}\)
B=\(\frac{\left|-2017\right|}{1}\)+\(\frac{2016}{\left|2\right|}\)+\(\frac{\left|-2015\right|}{3}\)+....+\(\frac{\left|-2\right|}{2016}\)+\(\frac{1}{2017}\)
