Bonjour,
x = 2/3 et y = -1/6
Donc l'inverse de la somme de x et y est :
1/(x+y) = 1/((2/3)+(-1/6)) = 1/((4/6)-(1/6)) = 1/((4-1)/6) = 1/(3/6) = 6/3 = 2

Bonsoir
x = 2 / 3
y = -1 / 6
Somme de x et y :
x + y
= 2 / 3 + (-1) / 6
= (2 x 2) / (3 x 2) + (-1) / 6
= 4 / 6 + (-1) / 6
= (4 - 1) / 6
= 3 / 6
= (3 / 3) / (6 / 3)
= 1 / 2
Inverse de 1 / 2
2 / 1 = 2
Donc l'inverse de la somme de x et y est 2.
Voilà j'espère avoir pu t'aider ^^
