Bonsoir,

Politesse :((

J = 1/8 - 7/12 + 7/6 + 7/16

J = 2/16 - 7/12 + 14/12 + 7/16

J = 9/16 + 7/12

J = 27/48 + 28/12

J = 55/12

K = 1/8 - 7/12 : 7/6 + 7/12

K = 1/8 - 7/12 x 6/7 + 7/12

K = 1/8 - 6/12 + 7/12

K = 1/8 + 1/12

K = 3/24 + 2/24

K = 5/24

M = (1/8 + 7/12)/(5/6 - 4/15)

M = (3/24 + 14/24)/(25/30 - 8/30)

M = 17/24 / 17/30

M = 17/24 x 30/17

M = 30/24

M = (6 x 5)/(6 x 4)

M = 5/4
