Question

Answer 1

a: Ta có: -5<0

\(0<\frac{1}{63}\)

Do đó: \(-5<\frac{1}{63}\)

b: \(\frac{-18}{17}<-1;-1<-\frac{999}{1000}\)

Do đó: \(-\frac{18}{17}<-\frac{999}{1000}\)

c: \(\frac{-17}{35}>\frac{-17.5}{35}=\frac{-1}{2};\frac{-1}{2}=\frac{-42,5}{85}>\frac{-43}{85}\)

Do đó: \(-\frac{17}{35}>-\frac{43}{85}\)

d: \(-0,76=\frac{-19}{25}\)

25<28

=>\(\frac{19}{25}>\frac{19}{28}\)

=>\(-\frac{19}{25}<-\frac{19}{28}\)

=>-0,76<-19/28
