Bonjour,
Exercice 24 :
a. 21/6 = 3x7/3x2 = 7/2 b. -14/12 = -7x2/6x2 = -7/6
c. -48/-18 = 48/18 = 6x8/6x3 = 8/3 d. 15/45 = 3x5/5x3x3 = 1/3
e. -16/24 = - 2x8/8x3 = -2/3
Exercice 27 :
Flèche rouge : - 7/8 ; flèche bleue : -1/8 ; flèche verte : 2/8
Exercice 31 :
a. 1/6 = 4/24 -3/8 = -8/24 5/12 = 10/24 -10/48 = -5/24
b. Ordre croissant :
-3/8 < -10/48 < 1/6 < 5/12
Bonne journée
