Bonsoir :)
Réponse en explications étape par étape :
- Question : Calculer :
A = 5/4 * 7/3
A = 35/12
B = 12 * 2/5
B = 24/5
C = - 9/2 * - 5/7
C = 45/14
D = - 6/7 * - 5/- 3
D = - 6/7 * 5/3
D = - 30/21
D = - (3 * 10)/(3 * 7)
D = - 10/7
E = 6 * 4/12
E = 6 * 1/3
E = 6/3
E = 2
F = - 1/3 * 1/7
F = - 1/21
Voilà
