Bonjour
K = 1/4 - 5/12 + 1/3
K = (1 x 3)/(4 x 3) - 5/12 + (1 x 4)/(3 x 4)
K = 3/12 - 5/12 + 4/12
K = (7 - 5)/12
K = 2/12
K = 2/(2 x 6)
K = 1/6
H = 3/10 x 20/8
H = 20/10 x 3/8
H = (2 x 10)/10 x 3/8
H = 2 x 3/8
H = 2/8 x 3
H = 2/(2 x 4) x 3
H = 1/4 x 3
H = 3/4
L = (16/3)/12
L = 16/3 x 1/12
L = 16/12 x 1/3
L = (4 x 4)/(4 x 3) x 1/3
L = 4/3 x 1/3
L = 4/9
N = (18/16)/(36/24)
N = 18/16 x 24/36
N = (2 x 9)/(2 x 8) x (12 x 2)/(12 x 3)
N = 9/8 x 2/3
N = 9/3 x 2/8
N = (3 x 3)/3 x 2/(2 x 4)
N = 3 x 1/4
N = 3/4
R = -5/4 : (-10/6)
R = 5/4 x 6/10
R = 5/4 x (2 x 3)/(2 x 5)
R = 5/4 x 3/5
R = 5/5 x 3/4
R = 3/4
T = -6/8 x (-22/3) x 9/66
T = (2 x 3)/(2 x 4) x 9/3 x 22/66
T = 3/4 x (3 x 3)/3 x 22/(3 x 22)
T = 3/4 x 3 x 1/3
T = 3/4 x 3/3
T = 3/4
W = (3/4 - (-3/36)) : (2 - 8/9)
W = (3/4 + 3/36) : [(2 x 9)/9 - 8/9]
W = [(3 x 3)/(3 x 4) + 3/(3 x 12)] : (18/9 - 8/9)
W = (9/12 + 3/12) : (10/9)
W = 12/12 x 9/10
W = 9/10
