G = 3/5 × 6/5G = 18/25

H = 4/3 × (- 13/9) × 6/-13H = - 52/27 x 6 / - 13H = 312/351
H = 39 x 8 / 39 x 9H = 8/9

I = 5 × 7/15I = 35/15I = 5 x 7 / 5 x 3I = 7/3

J = (- 55/6) × (-2/33)J = 110/198J = 22 x 5 / 22 x 9J = 5/9

K = 3/5 ÷ 4/7K = 3/5 x 7/4K = 21/20

L = -1/3 ÷ (- 5/9)L = - 1/3 x - 9/5
L = 9/15
L = 3 x 3 / 3 x 5
L = 3/5
