Bonsoir

Explications étape par étape :

P= -7/6-5/3+2/9

P = - 7/6 - 10/6 + 2/9

P = - 17/6 + 2/9

P =- 34/18 + 4/18

P= - 30/18

__________________________________________________________

Q= (4/3+2/15)-(3/4-1/8)

Q = (20/15 + 2/15) - ( 6/8 - 1/8)

Q = 22/15 - 5/8

Q = 176/120 - 75/120

Q = 101/120

Réponse:

p) -7/6 = -1,16

-5/3 = -1,66

2/9 = 0,22

p = -1,16-1,66+0,22 = -2,6

q ) 4/3 = 1,33

2/15 = 0,13

1,33+0,13 = 1,46

3/4 = 0,75

-1/8 = -0,125

0,75-0,125 = 0,625

1,46-0,625 = 0,835
