Exercice 2
Explications étape par étape:
J = 5/2 + 8/3
J = 5×3/2×3 + 8×2/3×2
J = 15/6 + 16/6
J = 31/6
K = 4/7 + 1/6
K = 4×6/7×6 + 1×7/6×7
K = 24/42 + 7/42
K = 31/42
L = 7/4 + 3/5
L = 7×5/4×5 + 3×4/5×4
L = 35/20 + 12/20
L = 47/20
M = 6/5 + 5/6
M = 6×6/5×6 + 5×5/6×5
M = 36/30 + 25/30
M = 61/30
voilà, mais essaie de t'exercer sinon tu ne vas rien comprendre.
