C pour l’exercice 2 aider moi svp

Bonjour,

Réponse :

x = 20

x = 15/2

x = 6

x = 27/4

Explications étape par étape :

Trouver x tel que :

x/12 = 5/3

x = 5 * 12/3

x = 5 * (3 * 4)/3

x = 5 * 4

x = 20

2/5 = 3/x

x = 3 * 5/2

x = 15/2

4/6 = x/9

x = 9/6 * 4

x = (3 * 3)/(3 * 2) * 4

x = 3/2 * 4

x = 3 * 4/2

x = 3 * (2 * 2)/2

x = 3 * 2

x = 6

2/x = 8/27

x = 2 * 27/8

x = 2/8 * 27

x = 2/(2 * 4) * 27

x = 1/4 * 27

x = 27/4
