Bonjour

F = 5/6 - 17/15

F = (5 x 5)/(6 x 5) - (17 x 2)/(15 x 2)

F = 25/30 - 34/30

F = -9/30

F = -(3 x 3)/(3 x 10)

F = -3/10

G = -9/24 x -36/-15

G = -9/15 x 36/24

G = -(3 x 3)/(3 x 5) x (12 x 3)/(12 x 2)

G = -3/5 x 3/2

G = -9/10

H = 10/18 : 45/24

H = 10/18 x 24/45

H = 10/45 x 24/18

H = (2 x 5)/(9 x 5) x (6 x 4)/(6 x 3)

H = 2/9 x 4/3

H = 8/27

H = 3/5 - 6/5 x 12/8

H = 3/5 - 6/5 x (3 x 4)/(4 x 2)

H = 3/5 - 6/5 x 3/2

H = 3/5 - 6/2 x 3/5

H = 3/5 - 3 x 3/5

H = 3/5 - 9/5

H = -6/5

I = (5/7 - 5/14) : 13/42

I = [(5 x 2)/(7 x 2) - 5/14] x 42/13

I = (10/14 - 5/14) x 42/13

I = 5/14 x 42/13

I = 42/14 x 5/13

I = (14 x 3)/14 x 5/13

I = 3 x 5/13

I = 15/13
