bonjour
Explications étape par étape :
2/5 = 16/40 = 12/30 = 24/60
14/12 = 21/18 = 70/60 = 7/6
9/12 = 3/4
15/60
12/45

2/5
14/12 = (2 x 7)/(2 x 6) = 7/6 ; (on simplifie par 2)
9/12 = (3 x 3)/(3 x 4) = 3/4 ; (on simplifie par 3)
16/40 = (2 x 8)/(5 x 8) = 2/5 ; (on simplifie par 8)
12/30 = (6 x 2)/(6 x 5) = 2/5 ; (on simplifie par 6)
21/18 = (3 x 7)/(3 x 6) =7/6 ; (on simplifie par 3)
3/4
70/60 = (7 x 10)/(6 x 10) =7/6 ; (on simplifie par 10)
15/60 = (1 x 15)/(4 x 15) = 1/4 ; (on simplifie par 15)
24/60 = (2 x 12)/(5 x 12) =2/5 ; (on simplifie par 12)
12/45 = (3 x 4)/(3 x 15) = 4/15 ; (on simplifie par 3)
7/6
