Bonjour
Calculer en détaillent les étapes, puis simplifier si possible
I=1/6x6/5=
I = 6/6 x 1/5
I = 1 x 1/5
I = 1/5
J=33/25x5/22=
J = 33/22 x 5/25
J = (3 x 11)/(2 x 11) x 5/(5 x 5)
J = 3/2 x 1/5
J = (3 x 1)/(2 x 5)
J = 3/10
K=14/15x30/49=
K = 14/49 x 30/15
K = (2 x 7)/(7 x 7) x (2 x 15)/15
K = 2/7 x 2
K = (2 x 2)/7
K = 4/7
L=56/13x26/64=
L = 56/64 x 26/13
L = (8 x 7)/(8 x 8) x (2 x 13)/13
L = 7/8 x 2
L = 7 x 2/8
L = 7 x 2/(2 x 4)
L = 7/4
