Ta có: \(\frac{-2017}{2018}+1=\frac{1}{2018}\)
\(\frac{-2018}{2019}+1=\frac{1}{2019}\)
Vì \(\frac{1}{2019}< \frac{1}{2018}\)
\(\Leftrightarrow\frac{-2018}{2019}+1< \frac{-2017}{2018}+1\)
\(\Leftrightarrow\frac{-2018}{2019}< \frac{-2017}{2018}\)
HOK TOT
So sánh hai phân số
A=2017/2018+2018/2019+2019/2020 và B=(2017+2018+2019)/(2018+2019+2020)
So sánh \(\frac{2017}{2018}+\frac{2018}{2019}và\frac{2015}{2016}+\frac{2016}{2017}\)
So sánh:
\(C=\frac{2018^{2019}-1}{2018^{2018}-1}\)và\(D=\frac{2017^{2018}+1}{2017^{2017}+1}\)
so sánh
A = \(\frac{2017}{2018}\) + \(\frac{2018}{2019}\) và B=\(\frac{2017+2018}{2018+2019}\)
So sánh: \(\frac{2017}{2018+2019}\)+ \(\frac{2018}{2017+2019}\)+ \(\frac{2019}{2017+2018}\)và 1
Bạn nào làm đúng mình tik cho
\(A=\frac{2019^{2018}+1}{2019^{2017}+1}\) \(B=\frac{2019^{2017}+1}{2018+1}\)
So sánh hai phân số
So sánh 2 số A và B
A=\(\frac{2017}{2018}\)+\(\frac{2018}{2019}\) B=\(\frac{2017+2018}{2018+2019}\)
So sánh phân số
\(\frac{2017}{2016}\) và \(\frac{2019}{2018}\)
So sánh 2 biểu thức:
M = \(\frac{2016}{2017}\)+\(\frac{2017}{2018}\)+\(\frac{2018}{2019}\)
N = \(\frac{2016+2017+2018}{2017+2018+2019}\)
