a) \(\frac{1}{8}>1\); \(\frac{-3}{8}< 1\)
=> \(\frac{1}{8}>\frac{-3}{8}\)
b)\(\frac{-3}{7}< 1\); \(2\frac{1}{2}=\frac{5}{2}>1\)=> \(\frac{-3}{7}< 2\frac{1}{2}\)
c)\(\frac{-3}{9}< 1\); \(0,1=\frac{1}{10}>1\)=> \(\frac{-3}{9}< 0,1\)
d) \(\frac{-2}{3}< 1\); \(\frac{3}{2}>1\)=> \(\frac{-2}{3}< \frac{3}{2}\)
