Bonsoir,
a. 0,3 = (0,3 x 10) / (1 x 10) = 3/10
b. 8,97 = (8,97 x 100) / (1 x 100) = 897/100
c. 0,67 = (0,67 x 100) / (1 x 100) = 67/100
d. 9,763 = (9,763 x 1 000) / (1 x 1 000) = 9 763/1 000
e. 21,74 = (21,74 x 100) / (1 x 100) = 2 174/100 = (2 x 1 087) / (2 x 50) = 1 087/50
f. 0,076 = (0,076 x 1 000) / (1 x 1 000) = 76/1 000 = (4 x 19) / (4 x 250) = 19/250
g. 251,08 = (251,08 x 100) / (1 x 100) = 25 108/100 = (4 x 6 277) / (4 x 25) = 6 277/25
h. 33,201 = (33,201 x 1 000) / (1 x 1 000) = 33 201/1 000.
i. 0,04 = (0,04 x 100) / (1 x 100) = 4/100 = (4 x 1) / (4 x 25) = 1/25.
