Answer 3

a)

Ta có:

\(\frac{27}{63}=\frac{3\cdot9}{7\cdot9}=\frac{3}{7};\frac{33}{88}=\frac{3\cdot11}{8\cdot11}=\frac{3}{8}\)

Mà 7>8

=>\(\frac{3}{7}>\frac{3}{8}\)

b)Ta có:
\(\frac{22}{45}< \frac{22}{44}=\frac{1}{2};\frac{17}{33}>\frac{17}{34}=\frac{1}{2}\)

=>\(\frac{22}{45}< \frac{1}{2}< \frac{17}{33}\)

Vậy......
