Answer 1

[Minh Nhân]

\(\dfrac{2023}{2022}=\dfrac{2022}{2022}+\dfrac{1}{2022}=1+\dfrac{1}{2022}\)

\(\dfrac{2021}{2020}=\dfrac{2020}{2020}+\dfrac{1}{2020}=1+\dfrac{1}{2020}\)

\(\dfrac{1}{2022}< \dfrac{1}{2020}\)

\(\Rightarrow\dfrac{2023}{2022}< \dfrac{2021}{2020}\)

Answer 2

[Nguyễn Lê Phước Thịnh]

\(\dfrac{2023}{2022}=1+\dfrac{1}{2022}\)

\(\dfrac{2021}{2020}=1+\dfrac{1}{2020}\)

mà \(\dfrac{1}{2022}< \dfrac{1}{2020}\)

nên \(\dfrac{2023}{2022}< \dfrac{2021}{2020}\)
