Bonjour
I= -33/25 x 45/44
I = -33/44 x 45/25
I = -(3 x 11)/(4 x 11) x (5 x 9)/(5 x 5)
I = -3/4 x 9/5
I = (-3 x 9)/(4 x 5)
I = -27/20
J= 35/-42 x 63/50
J = 35/50 x -63/42
J = (5 x 7)/(5 x 10) x (-3 x 21)/(2 x 21)
J = 7/10 x (-3/2)
J = (-3 x 7)/(2 x 10)
J = (-21/20)
K= -24/35 x -28/54
K = (-24/54) x (-28/35)
K = (6 x 4)/(6 x 9) x (7 x 4)/(7 x 5)
K = 4/9 x 4/5
K = (4 x 4)/(9 x 5)
K = 16/45
