Besoins d’aide pour c’est calcul, niveau seconde. Merci beaucoup

C = 5/11/-35/22 = 5 x 22/(11 x (-35) = 5 x 2 x 11/(11 x 5 x (-7)) = - 2/7

D = 2/3((1/3) + (7/15)) = 2/3((5/15) + (7/15)) = 2/3((5+7)/15) = 2/3) x 12/15  = 2 x 12)/3 x 15 = 8/15

E = 7/3) - 7/3 ÷ 5/6  ordre de priorité c'est la division

7/3/5/6 = (7 x 6)/(3 x5)  = 14/5

E = 7/3) - 14/5 = 35/15) - 14/15 = 21/15 = 7/5

F = ((3/5) - (1/3)) ÷ 3/5 = ((9/15 -(5/15)) ÷ 3/5 = (4/14) ÷ 3/5 = (4 x 5)/(3 x 14) = 10/21

G = (6 - (2/3) + (1/2)) - (5 + (5/3) - (3/2)) - (3 - (14/6) + (15/6))

  = (6 -(4/6) + (3/6)) - (5 + (10/6) - (9/6)) - (3 - (14/6) + (15/6))

 = (6 - (1/6)) - (5 + (1/6)) - (3 +( 1/6))

= 6 - 5 - 3  - 3 (1/6)

= - 2 - (1/2) = - 5/2
