Subsets of real numbers?
A real number is just an ordinary number. The set of real numbers include all numbers between negative and positive infinity. Real numbers are ordered, and thus do not include imaginary numbers. A subset of real numbers refers to a group, or subsection, of real numbers. For instance, the numbers between 5 and 22 are a subset of real numbers. Another example of a subset is all even numbers, or all odd numbers.

Asked in Numbers
What are the real numbers that is not a whole number?
Real numbers are all numbers which do not contain "i", when "i" represents the square root of -1. All numbers which do contain "i" are "imaginary numbers" and are not real numbers. This means that all numbers you'd ordinarily use are real numbers - all the counting numbers (integers) and all decimals are real numbers. So in answer to your question, all the real numbers that are not whole numbers are all the decimal numbers - including irrational decimals such as pi.
