Bsr,

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

R:  20/60 + 105/60  - 12/60 = 113/60
