Answer and Explanation:

To find : Name all sets of numbers to which each real number belongs ?

Solution :

Real number is defined as a set which contain all rational, irrational, integers, whole number, natural number.

Real number not contain an imaginary number i.e. i.

Now, Determining each number

1) 12 is real, rational, whole, integer.

2) -15 is real, rational, integer.

3) is real, rational

4) 3.18 is real, rational

5) is real and irrational because non-terminating and non-repeating.

6) 9.3 is real, rational

7) is a real, rational as it is repeating decimal.

8) is a real, rational, integer.

9) is real and irrational because non-terminating and non-repeating.

10) is real, rational , integer.

11) is real, irrational because non-terminating and non-repeating.

12) is real, rational, whole, integer.
