fractions égales = fractions proportionelles

moi perso j'utilise le produit en croix

donc

-6 * 24 = x * (-18)

x = 144/18

x= 8

et

x * 15 = 18*10

x= 180/15

x = 12

1)-6/x =-18/24

le produit en croix donne:

(-6  * 24) = (-18*x)

-18x = - 144

x = (-144) / (-18)

x = 8

2) x/18= 10/15

15x = 10*18

15x = 180

x = 180/ 15

x = 12
