Bonjour.

  1. [tex] \frac{280}{105} = \frac{56 \times 5}{21 \times 5} = \frac{56}{21} = \frac{7 \times 8}{7 \times 3} = \frac{8}{3} [/tex]
  2. [tex] \frac{108}{132} = \frac{4 \times 27}{4 \times 33} = \frac{27}{33} = \frac{3 \times 9}{3 \times 11} = \frac{9}{11} [/tex]

Voilà, allez bonne chance.
