Qui peut maider svp..... [tex] \frac{1}{5} + \frac{5}{2} + \frac{8}{10} [/tex] [tex] \frac{5}{3} + \frac{ - 5}{12} + \frac{1}{8} [/tex] aider moi.....​

Bonsoir,

Calculer :

A = 1/5 + 5/2 + 8/10

A = 1×2/5×2 + 5×5/2×5 + 8/10

A = 2/10 + 25/10 + 8/10

A = 2 + 25 + 8/10

A = 35/10

A = 7/2

B = 5/3 + -5/12 + 1/8

B = 5×8/3×8 + -5×2/12×2 + 1×3/8×3

B = 40/24 + -10/24 + 3/24

B = 40 - 10 + 3/24

B = 33/24

B = 11/8

Bonne soirée.
