Question

so sánh A và B mà không cần tính:

A=\(\dfrac{2000}{2001}\)+\(\dfrac{2001}{2002}\)

B=\(\dfrac{200+2001}{2001+2002}\)

Answer 1

Ta có : \(\dfrac{2000}{2001}>\dfrac{2000}{2001+2002}\)

\(\dfrac{2001}{2002}>\dfrac{2001}{2001+2002}\)

\(\Rightarrow\) \(\dfrac{2000}{2001}+\dfrac{2001}{2002}>\dfrac{2000+2001}{2001+2002}\)

Vậy A > B

Answer 2

mình viết nhầm nhé

B=\(\dfrac{2000+2001}{2001+2002}\)

Answer 3

\(A=\dfrac{2000}{2001}+\dfrac{2001}{2002}>\dfrac{2000}{2002}+\dfrac{2001}{2002}=\dfrac{2000+2001}{2002}>\dfrac{2000+2001}{2001+2002}\)
