Bonjour F=2/3-4/3:2/5 G=5+(1+1/8):3/4 H=(2/3-3):1/9 I=7/6+11/3*5/4 Merci d'avance ​

Bonjour,

F= 2/3-4/3:2/5

F = 2/3 - 4/3 x 5/2

F = (2 x 2) / (3 x 2) - 12/6

F = 4/6 - 12/16

F = - 8/6

F = (2 x - 4) / (2 x 3)

F = - 4/3

G=5+(1+1/8):3/4

G = 5 + [(1 x 8) / (1 x 8) + 1/8] : 3/4

G = 5 + (8/8 + 1/8) : 3/4

G = 5 + 9/8 x 4/3

G = 5 + 36/24

G = (5 x 2) / (1 x 2) + (12 x 3) / (12 x 2)

G = 10/2 + 3/2

G = 13/2

H=(2/3-3):1/9

H = [2/3 - (3 x 3) / (1 x 3)] : 1/9

H = (2/3 - 9/3) : 1/9

H = - 7/3 x 9

H = - 63/3

H = (3 x - 21) / (3 x 1)

H = - 21.

I=7/6+11/3*5/4

I = 7/6 + 55/12

I = (7 x 2) / (6 x 2) + 55/12

I = 14/12 + 55/12

I = 69/12

I = (3 x 23) / (3 x 4)

I = 23/4.
