Bonjour,M = 7/8 - 1/12
M = 21/24 - 2/24
M = - 19/24
N = - 4/9 + 5/12
N = - 16/36 + 15/36
N = - 1/36
P = - 7/6 - 5/3 + 2/9
P = - 21/18 - 30/18 + 4/18
P = - 51/18 + 4/18
P = - 47/18
Q = (4/3 + 2/15) - (3/4 - 1/8)
Q = (20/15 + 2/15) - (6/8 - 1/8)
Q = 22/15 - 5/8
Q = 176/120 - 75/120
Q = - 101/120

Bonjour,M = 7/8 - 1/12
M = (7x3)/(8x3) - (1x2)/(12x2)
M = 21/24 - 2/24
M = 19/24
N = -4/9 + 5/12
N = -16/36 + 15/36
N = -1/36
P = -7/6 - 5/3 + 2/9
P = -21/18 - 30/18 + 4/18
P = -51/18 + 4/18
P = -47/18
Q = (4/3 + 2/15) - (3/4 - 1/8)
Q = (20/15 + 2/15) - (6/8 - 1/8)
Q = 22/15 - 5/8
Q = 176/120 - 75/120
