Bonsoir est ce que vous pouvez me donner les réponses svp.

Bonjour

Calculer et donner le résultat sous la forme d'une fraction :

E = 4/3 x (3/14 + 6/14)

E = 4/3 x 9/14

E = 36/42

E = (6 x 6) / (6 x 7)

E = 6/7

F = (55/6 - 5/2) : 20

F = [55/6 - (5 x 3) / (2 x 3)] : 20

F = (55/6 - 15/6) : 20

F = 40/6 : 20

F = 40/6 x 1/20

F = 40/120

F = (40 x 1) / (40 x 3)

F = 1/3

G = (25/14 - 5/14) x (4/5 + 16/15)

G = 20/14 x [(4 x 3) / (5 x 3) + 16/15]

G = 20/14 x (12/15 + 16/15)

G = 20/15 x 28/15

G = 560/225

G = (5 x 12) / (5 x 45)

G = 12/45

H = (9/5 + 7/10) x 3/4 - 1/4

H = [(9 x 2) / (5 x 2) + 7/10] x 3/4 - 1/4

H = (18/10 + 7/10) x 3/4 - 1/4

H = 25/10 x 3/4 - (1 x 10) / (4 x 10)

H = 75/40 - 10/40

H = 65/40

H = (5 x 13) / (5 x 8)

H = 13/8.
