Bonjour,

G = -7/2 + 4/3

G = -(7 * 3)/(2 * 3) + (4 * 2)/(3 * 2)

G = -21/6 + 8/6

G = -13/21

H = 14/25 - (-3/5)

H = 14/25 + 15/25

H = 29/25

I = -4/5 * (-7/2)

I = 4/2 * 7/5

I = 2 * 7/5

I = 14/5

J = 7/5 * 3/2

J = 21/10

K = -3 + 5 * -6/7

K = -(3 * 7)/(1 * 7) - 30/7

K = -21/7 - 30/7

K = -41/7

L = 25/-12 * -16/35

L = 25/35 * 16/12

L = (5 * 5)/(7 * 5) * (4 * 4)/(4 * 3)

L = 5/7 * 4/3

L = 20/21
