Écrire s/forme de fractions :
a) 1/57 : 0,1 = 1/57:1/10 = 10/57
b) 17/0,3 = 17:3/10 = 17×10/3 = 170/3
c) 6/2,5 = 6:25/10 = 6×10/25 =
60/25 = 12/5
d) 34,47/1,1 = 34,47:11/10 =
34,47×10/11 = 344,7/11
e) 5,9/10,1 = 59/10:101/10=
59/10×10/101= 590/1010=59/101
f) 1/0,75 = 1×100/75 = 100/75 =4/3
Bonne soirée.
