1. Réponse Anonyme
B= (3/2 - 1/3) / (3/4 + 2/3)
B= (9/6 - 2/6) / (9/12 + 8/12)
B= (7/6) / (17/12)
B= 7/6 x 12/17
B= (7 x 2 x 2 x 3)/(2 x 3 x 17)
B= 14/17 -
2. Réponse maudmarine
B = (3/2 - 1/3) : (3/4 + 2/3)
B = (3 x 3 / 2 x 3 - 1 x 2 / 3 x 2) : (3 x 3 / 4 x 3 + 2 x 4 / 3 x 4)
B = (9/6 - 2/6) : (9/12 + 8/12)
B = 7/6 : 17/12
B = 7/6 x 12/17
B = 84/102
B = 6 x 14 / 6 x 17
B = 14/17
