a) 8−3​=8.3(−3).3​=24−9​

\(\frac{5}{- 12} = \frac{- 5}{12} = \frac{- 5.2}{12.2} = \frac{- 10}{24}\)

Vì \(\frac{- 9}{24} > \frac{- 10}{24}\) nên \(\frac{- 3}{8} > \frac{5}{- 12}\) \(\)

b)

\(\frac{3131}{5252}\) = \(\frac{3131}{5252}=\frac{3131:101}{5252:101}\) = \(\frac{31}{52}\) ​

\(\frac{31}{52} = \frac{31}{52}\)

Vì \(\frac{31}{52} = \frac{31}{52}\) nên \(\frac{3131}{5252} = \frac{31}{52}\)
