Bonsoir

Explications étape par étape

E = -7/5 / 6 + 1/5

E = (-7/5 * 1/6) + 1/5

E = -7/30 + 1/5

E = -1/30

F = 3/4 / 7/8 -3/7

F = (3/4 * 8/7) - 3/7

F = (3*4*2/4*7) - 3/7

F = 6/7 - 3/7

F = 3/7

G = 3/2 - 1/4 / 2 - 1/2

G = 3/2 - (1/4 * 1/2) - 1/2

G = 3/2 - 1/8 - 1/2

G = 12/8 - 1/8 - 4/8

G = 7/8

C = (4/5 - 11/3 ) * 25/43

C = (12/15 - 55/15) * 25/43

C = -43/15 * 25/43

C = (-43*25/15*43)

C = -25/15

C = (-5*5)/(5*3)

C = -5/3

D = - 2/5 : 3/15 + 2/15

D = (-2/5 * 15/3) + 2/15

D = (-2*5*3/5*3) + 2/15

D = -2 + 2/15

D = -30/15 + 2/15

D = -28/15
