The question is asking you to multiply a whole number and a fraction to get a product that is less than the whole number. Multiplying a whole number by a fraction will almost always result in a product less than the whole number so anything you use will work. some examples are:
2 * 1/2 = 1
4 * 1/2 = 2
6 * 1/2 = 3
And so on...
