Bonjour :)
Réponse en explications étape par étape :
- Question : Calculer :
A = 5/6 + 2/3
A = 5/6 + (2 * 2/3 * 2)
A = 5/6 + 4/6
A = 9/6
A = (3 * 3)/(3 * 2)
A = 3/2
B = 3/4 - 3/16
B = (3 * 4/4 * 4) - 3/16
B = 12/16 - 3/16
B = 9/16
C = 8/35 - 4/5
C = 8/35 - (4 * 7/5 * 7)
C = 8/35 - 28 35
C = - 20/35
C = - (4 * 5/7 * 5)
C = - 4/7
D = 13/25 - 2/5
D = 13/25 - (2 * 5/5 * 5)
D = 13/25 - 10/25
D = 3/25
E = - 31/18 - 4/3
E = - 31/18 - (4 * 6/3 * 6)
E = - 31/18 - 24/18
E = - 55/18
F = 1 - 5/42
F = 42/42 - 5/42
F = 37/42
Voilà
