60.
a) [tex] \frac{-2}{11}+ \frac{5}{22} = \frac{-4}{22} + \frac{5}{22} = \frac{1}{22} [/tex]
b) [tex] \frac{3}{-7}+ \frac{-9}{35} = \frac{-15}{35} + \frac{-9}{35} = \frac{-24}{35} [/tex]
c) [tex] \frac{8}{13} + \frac{-5}{-39} = \frac{24}{39} + \frac{5}{39} = \frac{29}{39} [/tex]
62.
a) [tex]2 +\frac{1}{3} - \frac{1}{6} = \frac{12}{6} + \frac{2}{6} - \frac{1}{6} = \frac{13}{6} [/tex]
b) [tex] \frac{3}{2} - \frac{-7}{6} + \frac{1}{4} = \frac{18}{12} - \frac{-14}{12} + \frac{3}{12} = \frac{35}{12} [/tex]
c) [tex] \frac{2}{7} + \frac{5}{-14} - \frac{1}{28} = \frac{8}{28} + \frac{-10}{28} - \frac{1}{28} = \frac{-3}{28} [/tex]
Voilà! :D Alors, bonne chance avec ton devoir!
