Réponse en explications étape par étape :
- Question : Calculer les expressions suivantes en détaillant les calculs :
A = 3/2 * 5/7
A = 15/14
B = - 4/11 * - 1/3
B = 4/33
C = 3 * - 7/5
C = - 21/5
D = - 5/4 * - 5/2
D = 25/8
E = 8/17 * - 5/3
E = - 40/51
F = - 13/-5 * (-2/-12)
F = 13/5 * 2/12
F = 13/5 * 1/6
F = 13/30
G = (-7/15) * (-8) * 2/3
G = 56/15 * 2/3
G = 112/45
H = - 1/2 * - 5/4 * - 3/2
H = 5/8 * - 3/2
H = - 15/16
Voilà
