Question
37. Calculer :
A = 5/6 + 2/3
B = 3/4 + -3/16
C = 8/35 + -4/5
38. Calculer :
A = 13/25 - 2/5
B = - 31/18 - 4/3
C = 1 - 5/42
39. Calculer :
A = 5/2 + 3/4 + -7/8
B = 4/15 + 2/5 - 7/30
Svp aidez moi
A = 5/6 + 2/3

Réponse :
37.
A=5/6 + 2/3 = 9/6
B= 3/4 + -3/6 = 9/16
C= 8/35 + -4/5 = -20/35 =4/7
38.
A= 13/25 - 2/5 = 3/25
B= -31/18 - 4/3 = -55/18
C= 1- 5/42 = 37/42
39.
A= 5/2 + 3/4 + -7/8 = 19/8 = 2/1
B= 4/15 + 2/5 - 7/30 = 13/30
Désolé j'ai pas pu simplifier toutes les fractions mais j'espère t'avoir aidé au maximum :)
