1. Réponse shanaclaes98
k=3/4+7/16+5/8
k=12/16+7/16+10/16
k=29/16
l=5/2x3/2x1/4
l=15/16
m=2+3/4+1/2
m=8/4+3/4+2/4
m=13/4
n=3x5/2x2/3
n=30/6 ou 5 -
2. Réponse MrEagle
K = 3/4 + 7/16 + 5/8
= 12/16 + 7/16 + 10/16
= 12/16 + 17/16
= 29/16
L = 5/2 x 3/2 x 1/4
= 15/4 x 1/4
= 15/16
M = 2 + 3/4 + 1/2
= 2 + 3/4 + 2/4
= 2 + 5/4
= 13/4
N = 3 x 5/2 x 2/3
= 3 x 10/6
= 5
