Explications étape par étape
Bonjour,
Effectue les calculs puis simplifie lorsque cela est possible.
G=7/8 - -5/3
G = 7/8 + 5/3
G = (7 x 3)/(8 x 3) + (5 x 8)/(3 x 8)
G = 21/24 + 40/24
G = 61/24
M=-2 + 5/6 - 23/10 - 3/-5
M = -2 + 5/6 - 23/10 + 3/5
M = (-2 x 60)/60 + (5 x 10)/(6 x 10) - (23 x 6)/(6 x 10) + (3 x 12)/(5 x 12)
M = -120/60 + 50/60 - 138/60 + 36/60
M = -258/60 + 86/60
M = -172/60
M = (4 x 43)/(4 x 15)
M = 43/15
H=-8/15 + -7/6
H = -(8 x 2)/(15 x 2) - (7 x 5)/(6 x 5)
H = -16/30 - 35/30
H = -51/30
J=5/6 - 5/8 - 5/24
J = (5 x 4)/(6 x 4) - (5 x 3)/(8 x 3) - 5/24
J = 20/24 - 15/24 - 5/24
J = 20/24 - 20/24
J = 0
K=1/-8 + 5/4 + -7/6
K = (-1 x 3)/(8 x 3) + (5 x 6)/(4 x 6) - (7 x 4)/(6 x 4)
K = -3/24 + 30/24 - 28/24
K = 30/24 - 31/24
K = -1/24
L=1 + -15/7 + -3/-5
L = 35/35 - (15 x 5)/(7 x 5) + (3 x 7)/(5 x 7)
L = 35/35 - 75/35 + 21/35
L = 56/35 - 75/35
L = -19/35
