Explications étape par étape
Bonjour
Simplifier les fractions :
20 40 50 60 66
--- ---- ---- ---- -----
42 88 350 120 180
20/42 = (2 x 10)/(2 x 21)
20/42 = 10/21
40/88 = (8 x 5)/(8 x 11)
40/88 = 5/11
50/350 = 50/(50 x 7)
50/350 = 1/7
60/120 = 60/(60 x 2)
60/120 = 1/2
66/180 = (6 x 11)/(6 x 30)
66/180 = 11/30
