Question

\(\frac{20}{21}va\frac{2000}{2001}\)so sánh phần bù nhé !

ai nhanh tay tick 5 lai nhe !

Answer 1

Ta có:

\(\frac{20}{21}=\frac{21}{21}-\frac{1}{21}=1-\frac{1}{21}\)

\(\frac{2000}{2001}=\frac{2001}{2001}-\frac{1}{2001}=1-\frac{1}{2001}\)

Vì \(\frac{1}{21}>\frac{1}{2001}\)

=> \(1-\frac{1}{21}< 1-\frac{1}{2001}\)

=> \(\frac{20}{21}< \frac{2000}{2001}\)

Answer 2

Ta có :

\(1-\frac{20}{21}=\frac{1}{21}\)

\(1-\frac{2000}{2001}=\frac{1}{2001}\)

Vì : \(\frac{1}{21}>\frac{1}{2001}\) Nên : \(\frac{20}{21}< \frac{2000}{2001}\)
