Which are the natural numbers integers rational numbers and irrational numbers 25 -17 -12 5 square root of 9 3.12 and 1 2 pi?

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 asking for 12 times pi). Rational numbers can be written as a fraction, so all of the numbers listed except pi are rational. The square root of 2 would be irrational, but since the square root of 9 is 3, it's rational. Pi is an irrational number.
