Bonjour,pouvez vous m’aidez pour l’exercice 33 car nous venons de commencer ce chapitre et je n’est pas compris merci beaucoup

Bonsoir,

a) 9/7 = (9 x 6)/(7 x 6) = 54/42

9/7 < 57/42

b) -16/3 = (-16 x 4)/(3 x 4) = -64/12

-23/4 = (-23 x 3)/(4 x 3) = -69/12

-16/3 > -69/12

c) -5/8 = (-5 x 3)/(8 x 3) = -15/24

-5/8 > -19/24

d) -7/5 = (-7 x 2)/(5 x 2) = -14/10

-3/2 = (-3 x 5)/(2 x 5) = -15/10

-7/5 > -3/2

e) 7/15 = (7 x 4)/(15 x 4) = 28/60

5/12 = (5 x 5)/(12 x 5) = 25/60

7/15 > 5/12

f) 7/12 = (7 x 3)/(12 x 3) = 21/36

7/9 = (7 x 4)/(9 x 4) = 28/36

7/12 < 7/9
