The numbers between 0.33 and 0.34 are infinite: in fact, since we can add an infinite number of digits after the comma, it means we can build infinite numbers between 0.33 and 0.34, which can be rewritten as 0.330 and 0.340. The problem asks for 3 numbers, so for instance we can use the following:
0.331, 0.335 and 0.338
All these 3 numbers are between 0.33 and 0.34.
