Answer 1

Phân số hả bn?

Answer 2

So sánh \(\frac{2018}{2019}\) và \(\frac{2019}{2020}\)

\(\frac{2018}{2019}\)=\(\frac{2019-1}{2019}\)=\(\frac{2019}{2019}\) - \(\frac{1}{2019}\)=1- \(\frac{1}{2019}\)

\(\frac{2019}{2020}\)=\(\frac{2020-1}{2020}\)=\(\frac{2020}{2020}\)-\(\frac{1}{2020}\)=1- \(\frac{1}{2020}\)

So sánh \(\frac{2018}{2019}\) và \(\frac{2019}{2020}\) ta thấy :

1=1 ;\(\frac{1}{2019}\)>\(\frac{1}{2020}\)

\(\Rightarrow\)1- \(\frac{1}{2019}\) < 1- \(\frac{1}{2020}\)

\(\Rightarrow\) \(\frac{2018}{2019}\) <\(\frac{2019}{2020}\)

Đúng thì nhớ tick cho mik nha!
