Bonjour est que vous pouvais aider a faire c est calcul

Réponse :

bonjour

A = 5/2 x 3/4 = 15/8

B = 5/2 : 3/4 = 5/2 x 4/3 = 20/6 = 10/3

C = - 1/6 - 2/9 =  - 3/18 - 4/18 = - 7/18

D = 7/9 x ( - 6) = - 42/9  = - 14 /3

E = 2 - 17/7 = 14/7 - 17/7 = - 3/7

F = 7/8 : 3 = 7/8 x 1/3 = 7/24

Bonjour

Explications étape par étape

A = 5/2 X 3/4 = 15/8

B = 5/2 : 3/4 = 5/2 X 4/3 = 20/6 = 10/3

C = -1/6 -2/9 = -1/6 X 9/9 -2/9 X 6/6 = -9/54 -12/54 = -21/54 : 3/3 = -7/18

D = 7/9 X (-6) = -42/9 = - 14/3

E = 2 -17/7 = 2 X 7/7 -17/7= 14/7 -17/7 = -3/7

F = 7/8 : 3 = 7/8 X 1/3 = 7/24
