Natural numbers are whole numbers from 1 upwards, so 25 and 5 are whole numbers. Since you didn't use commas, I can't tell if the last string of numbers is 12 times pi (not a natural number) or the numbers 1, 2, and pi (1 and 2 are natural numbers). Integers are whole numbers, so 25, -17, -12, 5, square root of 9 are all integers. (1 and 2 are as well, if they aren't…

So in answer to your question, all the real numbers that are not whole numbers are all the decimal numbers…
