bonjour
Explications étape par étape :
a. 6/9 = 3x2 /3x3 = 2/3
b. 8/14 = 4x2/7x2 =4/7
c.25/15 = 5x5/3x5= 3/5
d.16/12 =4x4/3x4= 4/3
a) 21/14= 3x7 /2x7 = 3/2
b) 12/27 =3x4 / 3x9 = 4/9
c) 36/42 =6x6 /6x7 =6/7
d) 30/35 =5x6 /5x7 = 6/7
a) 40/24 = 4x10/4x6 = 10/6 =2x5 / 2x3 = 5/3
b) 36/27 =12x3/9x3=12/9=4x3 /3x3 =4/3
c) 36/60 6x6/10x6=6/10=2x3/2x5=3/5
d) 45/75 =15x3 / 15x5 = 3/5
