RAM is simply the number of nucleons (neutrons and protons). Different elements necessarily have different numbers of protons, but there is nothing to say that when you add the neutrons, the total number of nucleons can't be the same another element.
RAMs CAN be whole numbers (or at least to 1dp): C, O, N, F, Na, Al, P etc.

but why may rams not be whole numbers?

Is there more information in the Q that you're not telling us?

no seriously thats it . it says word for word this : explain why ram may not be a whole number
It's to do with isotopes
So Chlorine can either have mass 35 or 37
35 appears 75% of the time and 37 is 25%
For a RAM, you take the weighted average of the mass and you end up with 35.5 for Chlorine
