Bonsoir
Explications étape par étape :
33/6 = (3*11)/(3*2) = 11/2
42/70 = (6*7)/(6*10) = 7/10
540/3600 = 54/360 = (6*3*3)/(6*3*2*10) = 3/20
3/1,6 = 30/16 = (3*5*2)/(8*2) = 15/8
1,35/1,8 = 135/180 = (5 *3*3*3)/(5*3*3*4) = 3/4
3,5 = 35/10 = (7*5)/(5*2) = 7/2
0,125 = 125/1000 = (1*125)/(125*8) = 1/8
(Si il faut diviser les 2 derniers alors :
3.5/0.125 = 3 500/125 = (5*7*25*4)/(5*25) = 28)
