$567 ÷ 567\dfrac{567}{568}$
$2025 ÷ 2025\dfrac{2025}{2026}$

答案

1. $567 ÷ 567\dfrac{567}{568}$
$=567÷ \dfrac{567× 568 + 567}{568}$
$=567÷ \dfrac{567× (568 + 1)}{568}$
$=567× \dfrac{568}{567× 569}$
$=\dfrac{568}{569}$
2. $2025 ÷ 2025\dfrac{2025}{2026}$
$=2025÷ \dfrac{2025× 2026 + 2025}{2026}$
$=2025÷ \dfrac{2025× (2026 + 1)}{2026}$
$=2025× \dfrac{2026}{2025× 2027}$
$=\dfrac{2026}{2027}$
