Coucou ❤️
Exercice 2 :
70/294 = 2x5x7/2x3x7x7 = 5/3x7 =5/21
203/631 = 203/631
198/741 = 2x3x3x11 / 3x13x19 = 2x3x11 / 13x19 = 66/247
Exercice 3 :
20/24 = 2x2x5 / 2x2x2x3 = 5/2x3 = 5/6.
100/75 = 2x2x5x5 / 3x5x5 = 2x2 / 3 = 4/3.
36/42 = 2x2x3x3 / 2x3x7 = 2x3 /7 = 6/7.
35/49 = 5x7 / 7x7 = 5/7.
J’espère que tu comprends parce que ce n’ai pas évident à écrire…!
