Bonjour
H = -2/7 + 3/14
H = (-2 x 2)/(2 x 7) + 3/14
H = -4/14 + 3/14
H = -1/14
J = -5/21 - 7/3
J = -5/21 - (7 x 7)/(3 x 7)
J = -5/21 - 49/21
J = -54/21
J = -(18 x 3)/(7 x 3)
J = -18/7
G = -5 + 6/-5
G = -(5 x 5)/5 - 6/5
G = -25/5 - 6/5
G = -31/5
K = 1/17 - 5/51
K = 3/(3 x 17) - 5/51
K = 3/51 - 5/51
K = -2/51
U = 7/4 - (-1/8 - 3/10)
U = 7/4 - (-5/40 - 12/40)
U = 7/4 - (-17/40)
U = 7/4 + 17/40
U = 70/40 + 17/40
U = 87/40
W = 3/4 - (-5/12 - 1/3)+ (-2 - 1/6)
W = 3/4 - (-5/12 - 4/12) + (-12/6 - 1/6)
W = 3/4 - (-9/12) - 13/6
W = 3/4 + 3/4 - 13/6
W = 9/12 + 9/12 - 26/12
W = 18/12 - 26/12
W = -8/12
W = -2/3
R = 2/3 - (-7/4) - 1/5
R = 2/3 + 7/4 - 1/5
R = 40/60 + 105/60 - 12/60
R = 145/60 - 12/60
R = 133/60
P = -11 + 1/11 + 1/6 - 6
P = -17 + 6/66 + 11/66
P = -17 + 17/66
P = -1122/66 + 17/66
P = -1105/66
