Bonjour,
Expliquer pourquoi ces fractions ne sont pas égales:
a)2/7 et 3/8
2/7 = (2 x 8)/(7 x 8) = 16/56
3/8 = (3 x 7)/(8 x 7) = 21/56
[tex]/boxed{2/7 different de 3/8}[/tex]
b)5/4 et 6/11
5/4 = (5 x 11)/(4 x 11) = 55/44
6/11 = (6 x 4)/(11 x 4) = 24/44
[tex]\boxed{5/4 different de 6/11}[/tex]
c)3/2 et 4/3
3/2 = (3 x 3)/(2 x 3) = 9/6
4/3 = (4 x 2)/(3 x 2) = 8/6
[tex]\boxed{3/2 different de 4/3}[/tex]
d)1/2 et 12/23
1/2 = (1 x 23)/(2 x 23) = 23/46
12/23 = (12 x 2)/(23 x 2) = 24/46
[tex]\boxed{1/2 different de 12/23}[/tex]
