1. Réponse nonotata
e = 2/3 -7/3x8/21e = 2/3 - 7/3 x8/7*3
e = 2/3 -8/9
e = 6/9-8/9
e = -2/9
f = 11 : (2/3-5/2)
f = 11 :(4/6-15/6)
f = 11 : -11/6
f = 11 x -6/11
f = -6

2. Réponse maudmarine
E = 2/3 –7/3 × 8/21
E = 2/3 - 56/63
E = 2 x 21 / 3 x 21 - 56/63
E = 42/63 - 56/63
E = 14/63
E = 7 x 2 / 7 x 9
E = 2/9
F = 11 ÷ (2/3 – 5/2)
F = 11 : (2 x 2 / 3 x 2 - 5 x 3 / 2 x 3)
F = 11 : (4/6 - 15/6)
F = 11 : - 11/6
F = 11 x - 6/11
F = - 66/11
F = 11 x - 6 / 11 x 1
F = - 6
