A. \(\frac{3}{124}\);\(\frac{1}{41}\);\(\frac{5}{207}\);\(\frac{2}{83}\) 

B.  \(\frac{134}{43}\);\(\frac{55}{21}\);\(\frac{74}{19}\); \(\frac{116}{37}\)

So sánh các phân số sau:

a)\(\dfrac{3}{124};\dfrac{1}{41};\dfrac{5}{207};\dfrac{2}{83}\)

b) \(\dfrac{27}{82};\dfrac{26}{75}\)

c) \(\dfrac{134}{43};\dfrac{55}{21};\dfrac{74}{19};\dfrac{116}{37}\)

d) \(\dfrac{-2525}{2929};\dfrac{-217}{245}\)

e) \(\dfrac{-49}{78};\dfrac{64}{-95}\)

So sánh các phân số:

a)\(\frac{3}{124},\frac{1}{41},\frac{5}{207},\frac{2}{83}\)

b)\(\frac{134}{43},\frac{55}{21},\frac{74}{19},\frac{116}{37}\)

c)\(\frac{-2525}{2929},,\frac{-217}{245}\)

d)\(\frac{27}{28},\frac{26}{75}\)

e)\(\frac{-49}{78}.\frac{64}{-95}\)

bài 1:So sánh các phân số sau:

a) \(\frac{3}{124}\);\(\frac{1}{41}\);\(\frac{5}{207}\);\(\frac{2}{83}\)

b)\(\frac{134}{43}\);\(\frac{55}{21}\);\(\frac{74}{19}\);\(\frac{116}{37}\)

c) A=\(\frac{54.107-53}{53.107+54}\)và B=\(\frac{135.269-133}{134.269+135}\)

d)\(\frac{-49}{78}\);\(\frac{64}{-95}\)
