7/3x = 2
x = 2 * 3/7
x = 6/7
7/3x = -5
x = -5 * 3/7
x = -15/7
7/3x = 1/3
x = 1/3 * 3/7
x = 3/21 = 1/7
7/3x = 28/9
x = 28/9 * 3/7
x = ......
Bonjour !
1) 2 / 7/3 = 2 * 3/7 = 6/7
2) -5 / 7/3 = -5 * 3/7 = -15/7
3) 1/3 / 7/3 = 1/3 * 3/7 = 1/7
4) 28/9 / 7/3 = 28/9 * 3/7 = 4/3
J'espère t'avoir aidé. Bon courage !
