Câu 1:

a; \(\dfrac{-9}{4}\) < 0; \(\dfrac{1}{3}\) > o

\(\dfrac{-9}{4}\) < \(\dfrac{1}{3}\)

b; \(\dfrac{-8}{3}\) < - 1

    \(\dfrac{4}{-7}\) > - 1

Vậy  \(\dfrac{-8}{3}\) < \(\dfrac{4}{-7}\)

c; \(\dfrac{9}{-5}\) < - 1

\(\dfrac{7}{-10}\)  > - 1

Vậy \(\dfrac{9}{-5}\) < \(\dfrac{7}{-10}\)

Câu 2:

a; Viết các phân số theo thứ tự tăng dần 

\(\dfrac{-1}{2}\); \(\dfrac{2}{7}\); \(\dfrac{2}{5}\)

b;  \(\dfrac{-11}{4}\); \(\dfrac{-7}{3}\); \(\dfrac{12}{5}\) 

\(\dfrac{1}{3}\) = \(\dfrac{8}{24}\); \(\dfrac{1}{8}\) = \(\dfrac{3}{24}\); \(\dfrac{1}{6}\) = \(\dfrac{4}{24}\); \(\dfrac{1}{12}\) = \(\dfrac{2}{24}\); \(\dfrac{7}{24}\)
