Sagot :
Salut,
A. 8/15 + 11/15 = 8/15 + 33/15 = 41/15
B. 5/6 - 7/24 = 20/24 -7/24 = 13/24
C. 7/12 - 5/3 = 7/12 - 20/12 = -13/12
En espérant que ceci t’aidera :)

Réponse:
a= 8/15 + 11/5
a= 8/15 + 11×3/5×3
a= 8+33/15
a= 41/15
b= 5/6 - 7/24
b= 5×4/6×4 - 7/24
b= 20-7/24
b= 13/7
c= 7/12 - 5/3
c= 7/12 - 5×4/3×4
c= 7-20/12
c= -13/12
