Réponse : 5*2 / 4*2 = 10/8
5 / 6 + 1 / 3 = 5/6 + 1*2 / 3*2 = 5/6 + 2/6 = 7/6
3/4 + 5/12 = 3*3 / 4*3 + 5/12 = 9/12 + 5/12 = 14/12
7/4 - 7/12 = 7*3 / 4*3 - 7/12 = 21/12 - 7/12 = 14/12
(5+2) / (4+2) = 7/6
13/6 - 1 = 13/6 - 1/1 = 13/6 - 1*6/1*6 = 13/6 - 6/6 = 7/6
13/24 + 1/8 + 1/2 = 13/24 + 1*3 / 8*3 + 1*12 / 2*12 = 13/24 + 3/24 + 12/24 = 28/24
5/3 - 5/12 - 1/24 = 5*8 / 3*8 - 5*2 / 12*2 - 1/24 = 40/24 - 10/12 - 1/24 = 29/24
J'espère que je t'aurais aidé, Bonne soirée,
