Bonjour,

- 2/9 = (- 2 x 4) / (9 x 4) = - 8/36

14/36

- 1/18 = (- 1 x 2) / (18 x 2) = - 2/36

5/6 = (5 x 6) / (6 x 6) = 30/36

- 1/2 = (- 1 x 18) / (2 x 18) = - 18/36

- 13/36

3/2 = (3 x 18) / (2 x 18) = 54/36

- 7/6 = (- 7 x 6) / (6 x 6) = - 42/36

4/9 = (4 x 4) / (9 x 4) = 16/36

- 3/4 = (- 3 x 9) / (4 x 9) = - 27/36

Donc :

- 7/6 < - 3/4 < - 1/2 < - 13/36 < - 2/9 < - 1/18 < 14/36 < 4/9 < 5/6 < 3/2
