[Kiki :))]

Không quy đồng mẫu só hãy so sánh:

\(A=\frac{-9}{2016}+\frac{-19}{2017}\)và \(B=\frac{-9}{2017}+\frac{-19}{2016}\)

Answer 1

[Ken Tom Trần]

\(A=\left(\frac{-9}{2016}+\frac{-9}{2017}\right)+\frac{-10}{2017}\\ B=\left(\frac{-9}{2017}+\frac{-9}{2016}\right)+\frac{-10}{2016}\\ Do\frac{-10}{2017}>\frac{10}{2016}\)

nên A>B
