Question

[Ngô Thái An]

So sánh phân số
 63/64 và 32/33
2020/2019 và 2022/2021

Answer 1

[Sakuvy]

$1-\frac{63}{64}=\frac{1}{64}$

$1-\frac{32}{33}=\frac{1}{33}$

Vì $\frac{1}{64}<\frac{1}{33}\Rightarrow \frac{63}{64}>\frac{32}{33}$

Vậy $\frac{63}{64}>\frac{32}{33}$

Answer 2

[Sakuvy]

$\frac{2020}{2019}-1=\frac{1}{2019}$

$\frac{2022}{2021}-1=\frac{1}{2021}$

Mà $\frac{1}{2019}>\frac{1}{2021}$

$\Rightarrow \frac{2020}{2019}>\frac{2022}{2021}$

Vậy $\frac{2020}{2019}>\frac{2022}{2021}$
