Bonjour =
1/6 = 11 x 1/11 x 6= 11/66
4/5 = 4 x 6/5 x 6= 24/30
3/8 = 3 x 4/8 x 4 = 12/32
3/4 = 3 x 11/4 x 11 = 33/44
1/5 = 1 x 3/5 x 3 = 3/15
1/3 = 1 x 3/3 x 3 = 3/9
1/7 = 7 x 5/1 x 5 =5/35
2 = 2 x 2/2 = 4/2
5/7 = 7 x 9/5 x 9 = 45/63
2/5 = 2 x 5/5 x 5 = 10/25
2)
5/2 = 5 x 50/2 x 50 = 250/100 = 250%
5/10 = 5 x 10/10 x 10 = 50/100 = 50%
je te laisse faire le reste c’est très simple j’espère t’avoir aidé!
