$=2022÷\frac {2022×2023+2022}{2023}$
$=2022÷\frac {2022×(2023+1)}{2023}$
$=2022÷\frac {2022×2024}{2023}$
$=2022×\frac {2023}{2022×2024}$
$=\frac {2023}{2024}$
【解析】:
$2022÷2022\frac{2022}{2023}$
$=2022÷\frac{2022×2023+2022}{2023}$
$=2022÷\frac{2022×(2023+1)}{2023}$
$=2022×\frac{2023}{2022×2024}$
$=\frac{2023}{2024}$
