Well, if the product has two decimal places and it is known that one factor has none, then the other factor must have two decimal places. Where would those two decimal places in the product come from otherwise?
Some examples:
1 * 34.44 = 34.44
2 * 17.22 = 34.44
In both cases, the non-integer factor had two decimal places.
Hope I helped, and let me know if you have any questions! :D
