a. [tex]\frac{3+5}{8} = \frac{8}{8} = 1[/tex]
b.[tex]\frac{-3+7}{10} = \frac{4}{10} = \frac{2}{5}[/tex]
c.[tex]\frac{2-5}{6} = \frac{-3}{6} = \frac{-1}{2}[/tex]
d. se amplifica [tex]\frac{-7}{3}[/tex] cu 2 dand [tex]\frac{-14-5}{6} = \frac{-19}{6}[/tex]
e. se amplifica -1 cu 12 dand [tex]\frac{-12-5}{12} = \frac{-17}{12}[/tex]
f. se amplifica 1 cu 8 dand [tex]\frac{8-7}{8} = \frac{-1}{8}[/tex]
