Bonsoir je n’arrive pas l’exercice pouvez vous m’aider l’ex ci-joint

Bonsoir,

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

-1/4 * 16/9 = -16/36  = -4/18 = -2/9

1/2- 48/36=

1/2 - 24/18

= 1/2 - 12/9

= 1/2- 4/3

= 3/6 - 8/6

= -5/6

Réponse:

E= (1×2/2×2 - 3/4) ×16/9

= (2/4 - 3/4) × 16/9

= -1/4 × 16/9

= -16/36

= -4/9

F= 1/2 - 3×16/4×9

= 1/2 - 48/36

= 1×18/2×18 - 48/36

= 18/36 - 48/36

= -30/36

= -5/6
