Bonjour pouvez-vous m’aider à mon exercice de maths s’il vous plaît merci d’avance :)

Bonjour,

G = - 5 + 6/- 5

G = - 5 - 6/5

G = (- 5 x 5) / (1 x 5) - 6/5

G = - 25/5 - 6/5

G = - 31/5

H = - 2/7 + 3/14

H = (- 2 x 2) / (7 x 2) + 3/14

H = - 4/14 + 3/14

H = - 1/14

J = - 5/21 - 7/3

J = - 5/21 - (7 x 7) / (3 x 7)

J = - 5/21 - 49/21

J = - 54/21

J = (3 x - 18) / (3 x 7)

J = - 18/7

K = 1/17 - 5/51

K = (1 x 3) / (17 x 3) - 5/51

K = 3/51 - 5/51

K = - 2/51

P = - 11 + 1/11 + 1/6 - 6

P = (- 11 x 66) / (1 x 66) + (1 x 6) / (11 x 6) + (1 x 11) / (6 x 11) - (6 x 66) / (1 x 66)

P = - 726/66 + 6/66 + 11/66 - 396/66

P = - 1 105/66

R = 2/3 - - 7/4 - 1/5

R = 2/3 + 7/4 - 1/5

R = (2 x 20) / (3 x 20) + (7 x 15) / (4 x 15) - (1 x 12) / (5 x 12)

R = 40/60 + 105/60 - 12/60

R = 133/60.

U = 7/4 - (- 1/8 - 3/10)

U = (7 x 10) / (4 x 10) - [(- 1 x 5) / (8 x 5) - (3 x 4) / (10 x 4)]

U = 70/40 - (- 5/40 - 12/40)

U = 70/40 + 17/40

U = 87/40.

W = 3/4 - (- 5/12 - 1/3) + (- 2 - 1/6)

W = (3 x 3) / (4 x 3) - [- 5/12 - (1 x 4) / (3 x 4)] + [(- 2 x 12) / (1 x 12) - (1 x 2) / (6 x 2)]

W = 9/12 - (- 5/12 - 4/12) + (- 24/12 - 2/12)

W = 9/12 + 9/12 - 26/12

W = 18/12 - 26/12

W = - 8/12

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

W = - 2/3
