Question

 

so sánh

B=\(\dfrac{2024}{2025}\)

A=\(\dfrac{2023}{2024}\)

Answer 1

B = \(1-\dfrac{1}{2025}\)   \(A=1-\dfrac{1}{2024}\)

Vì \(\dfrac{1}{2025}< \dfrac{1}{2024}\)

Nên B>A

Answer 2

Ta có :

\(\dfrac{2023}{2024}\)=\(\dfrac{2024-1}{2024}\)=\(\dfrac{2024}{2024}\)-\(\dfrac{1}{2024}\)=1-\(\dfrac{1}{2024}\)

\(\dfrac{2024}{2025}\)=\(\dfrac{2025-1}{2025}\)=\(\dfrac{2025}{2025}\)-\(\dfrac{1}{2025}\)=1=\(\dfrac{1}{2025}\)

Ta thấy: \(\dfrac{1}{2024}\) lớn hơn \(\dfrac{1}{2025}\)

Nên : \(\dfrac{2023}{2024}\) lớn hơn \(\dfrac{2024}{2025}\)

⇒A lớn hơn B
