Bài 52 :

a) 14/21 = 2/3 và 60/72 = 5/6

Vì 2/3 = 4/6 < 5/6 nên 2/3 < 5/6

Bài 53 :

a) Vì 200 < 314 nên 17/200 > 17/314

b) Ta có 11/54 < 11/37 < 22/37 nên 11/54 < 22/37

sxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

a)17/200>17/314

b)11/54=22/108<22/37

c)141/893=3/19;159/901=3/17 nên 141/893<159/901

Kết bn với mik nha!

a: \(-\dfrac{49}{211}< 0\)

\(0< \dfrac{13}{1999}\)

Do đó: \(-\dfrac{49}{211}< \dfrac{13}{1999}\)

b: \(\dfrac{311}{256}>1\)

\(1>\dfrac{199}{203}\)

Do đó: \(\dfrac{311}{256}>\dfrac{199}{203}\)

c: \(\dfrac{99}{-98}< 0\)

\(0< \dfrac{33}{49}\)

Do đó: \(\dfrac{99}{-98}< \dfrac{33}{49}\)

d: \(\dfrac{105}{106}< 1\)

\(1< \dfrac{94}{93}\)

Do đó: \(\dfrac{105}{106}< \dfrac{94}{93}\)

17/200>17/314

11/54<22/37

141/893<159/901

17/200>17/314

11/54<22/37

141/893<159/901

Ta có:

\(\dfrac{-49}{211}< 0;\dfrac{13}{1999}>0\)

⇒ \(\dfrac{-49}{211}< \dfrac{13}{1999}\)

-49/211<0<13/1999

-49/211<0<13/1999
