Réponse:
a.4/3+7/3=4+7/3=11/3
b.2/7+8/7=2+8/7=10/7
c.9/5-7/5=9-7/5=2/5
d.4/6+11/6-5/6=4+11-5/6=10/6
e.5/2-3/2-7/2=5-3-7/2=(-5)/2
a.
[tex] \frac{4}{3} + \frac{7}{3} = \frac{11}{3} [/tex]
b.
[tex] \frac{2}{7} + \frac{8}{7} = \frac{10}{7} [/tex]
c.
[tex] \frac{9}{5} - \frac{7}{5} = \frac{2}{5} [/tex]
d.
[tex] \frac{4}{6} + \frac{11}{6} - \frac{5}{6} = \frac{5}{3} [/tex]
e.
[tex] \frac{5}{2} - \frac{3}{2} - \frac{7}{2} = - \frac{5}{2} [/tex]
