a/ \(\dfrac{-3}{100}\) và \(\dfrac{2}{-3}\)

b/\(\dfrac{-3}{5}\) và \(\dfrac{2}{-3}\)

c/ \(\dfrac{-5}{4}\) và \(\dfrac{-3}{8}\)

d/ \(-\dfrac{2}{3}\) và \(\dfrac{3}{-4}\)

e/ \(\dfrac{267}{-268}\) và \(\dfrac{-1347}{1343}\)

Answer 1

a: -3/100=-9/300; -2/3=-200/300

=>-3/100>-2/3

b: -3/5=-9/15

-2/3=-10/15

=>-3/5>-2/3

c: -5/4<-1<-3/8

d: -2/3=-8/12; -3/4=-9/12

=>-2/3>-3/4

e: -267/268>-1

-1>-1347/1343

=>-267/268>-1347/1343
