F=-5/2+-2/3--7/4
F = (- 5 x 6) / (2 x 6) - (2 x 4) / (3 x 4) + (7 x 3) / (4 x 3)
F = - 30/12 - 8/12 + 21/12
F = - 17/12
G=24/35×-45/16+11/2.
G = - 1080/560 + 11
/2
G= (40 x 27) / (40 x 14) + (11 x 7) / (2 x 7)
G = 27/14 + 77/14
G = 104/14
G = (2 x 52) / (2 x 7)
G = 52/7
H=-5/4×(7/15_13/20)
H = - 5/4 x [(7 x 4) / (15 x 4) - (13 x 3) / (20 x 3)]
H = - 5/4 x (28/60 - 39/60)
H = - 5/4 x - 11/60
H = 55/240
H = (5 x 11) / (5 x 48)
H = 11/48
J=3/8--5/8×(3/5-7/3)
J = 3/8 + 5/8 x [(3 x 3) / (5 x 3) - (7 x 5) / (3x 5)]
J = 3/8 + 5/8 x (9/15 - 35/15)
J = 3/8 + 5/8 x -26/15
I = 3/8 - 130/120
I = 3/8 - (10 x 13) / (10 x 12)
I = 3/8 - 13/12
I = (3 x 3) / (8 x 3) - (13 x 2) / (12 x 2)
I = 9/24 - 26/24
I = - 17/24
k=(-7/6+1/8)×(2/5-6/7)
K = [(- 7 x 4) / (6 x 4) + (1 x 3) / (8 x 3)] x [(2 x 7) / (5 x 7) - (6 x 5) / (7 x 5)]
K = (- 28/24 + 3/24) x (14/35 - 30/35)
K = - 25/24 x - 16/35
H = 400/840
H = (40 x 10) / (40 x 21)
H = 10/21.
