bonjour
D = 5 + ( 1 + 1/8) : 3 /4
D = 5 + ( 8/8 + 1/8) : 3/4
D = 5 + 9/8 : 3/4
D = 5 + 9/8 * 4/3
D = 5 + 36/24
D = 5 + 3/2
D = 10/2 + 3/2
D = 13/2
G = 7/3 - 4/3 : 2/5
G = 7 /3 - 4/3 * 5/2
G = 7/3 - 20/6
G = 14/6 - 20/6
G = - 6 /6
G = - 1
Bonjour !
D = 5 + (1 + 1/8) : 3/4
D = 5 + (8/8 + 1/8) : 3/4
D = 5 + 9/8 * 4/3
D = 5 + 36/24
D = 5 + 9/6
D = (5 * 6)/(1 * 6) + 9/6
D = 30/6 + 9/6
D = 39/6 = (13 * 3)/(3 * 2) = 13/2.
E = 7/3 - 4/3 : 2/5
E = 7/3 - 4/3 * 5/2
E = 7/3 - 20/6
E = 14/6 - 20/6
E = -6/6 = -1.
Bonne journée !
