2016/2015 lớn hơn k và kết bạn nha
trả lời
2016/2015 > 2017/2016
nhớ k cho mình nha
học tốt
Bạn ghi bài rõ ra nha!!!
\(\frac{2016}{2015}=\frac{2015+1}{2015}=1+\frac{1}{2015}\)
\(\frac{2017}{2016}=\frac{2016+1}{2016}=1+\frac{1}{2016}\)
Do \(\frac{1}{2015}>\frac{1}{2016}\)
=> \(1+\frac{1}{2015}>1+\frac{1}{2016}\)
Hay\(\frac{2016}{2015}>\frac{2017}{2016}\)
ta có 2016/2015 -1 = 1/2015
2017/2016-1=1/2016
mà 2015<2016 => 1/2015 > 1/2016
suy ra 2016/2015 > 2017/2016
\(\frac{2016}{2015}=\frac{2015+1}{2015}=1+\frac{1}{2015}\left(1\right)\)
\(\frac{2017}{2016}=\frac{2016+1}{2016}=1+\frac{1}{2016}\left(2\right)\)
Từ 1 và 2 \(=>1+\frac{1}{2015}>1+\frac{1}{2016}\)
Hay \(\frac{2016}{2015}>\frac{2017}{2016}\)
\(\frac{2016}{2015}\)và \(\frac{2017}{2016}\)
Xét
\(\frac{2016}{2015}=\frac{2015+1}{2015}=1+\frac{1}{2015}\)
\(\frac{2017}{2016}=\frac{2016+1}{2016}=1+\frac{1}{2016}\)
\(\Rightarrow1+\frac{1}{2015}< 1+\frac{1}{2016}\)
