G= 21/24 + 40/24 = 61/24
H: -16/30 - 35/30 = - 51/30= -17/10
J: -12/40 -45/40 +56/40 + 6/40 = 5/40 = 1/8
K: -3/24 +30/24 -28/24 = -1/24
L: 35/35 - 75/35 + 21/35 = -19/35
M: 120/60 +50/60 - 138/60 + 12/60 = 44/60 = 22/30 = 11/15
N: 20/24 -15/24 -5/24 = 0
P: - 726/66 + 6/66 +11/66 - 396/66 = - 1105/66
