Bonjour.
a.
[tex] \frac{7}{4} + \frac{1}{8} = \frac{14}{8} + \frac{1}{8} = \frac{15}{8} [/tex]
b.
[tex] \frac{1}{2} + \frac{3}{26} = \frac{13}{26} + \frac{3}{26} = \frac{16}{26} = \frac{8}{13} [/tex]
c.
[tex] \frac{8}{4} + \frac{4}{8} = \frac{16}{8} + \frac{4}{8} = \frac{20}{8} = \frac{5}{2} [/tex]
d.
[tex] \frac{13}{7} + \frac{13}{21} = \frac{39}{21} + \frac{13}{21} = \frac{52}{21} [/tex]
e.
[tex] \frac{1}{11} + \frac{2}{33} = \frac{3}{33} + \frac{2}{33} = \frac{5}{33} [/tex]
f.
[tex] \frac{7}{10} + \frac{9}{2} = \frac{7}{10} + \frac{45}{10} = \frac{52}{10} = \frac{26}{5} [/tex]
Voilà j'ai fini !
Allez, BONNE CHANCE !!!
