9 belongs in the sets: -Natural number set, positive whole numbers -Integer number set, whole numbers -Rational number set, numbers that are not never ending -Real number set, basic numbers without i and that can be expressed in say amounts of apples -Complex number set, the set that contains both real and unreal numbers

Whole numbers are usually defined as the number 0,1,2,3,4,5,6.... where "...." means it goes on forever. These are the natural numbers with the number 0 added to them. So the natural numbers are 1,2,3,4,5,6...The integers are all the whole number and all the negatives of the natural numbers....-4,-3,-2,-1,0,1,2,3,4...So every whole number is an integer.Every natural number is an integer.Every integer is NOT a whole number. ( look at -2)Every integer is NOT a natural number. ( look at -3)The set of integers contains the set of natural numbers and contains the set of whole numbers.The set of whole numbers contains the set of natural numbers.

Irrational.

It belongs to any set that contains it: for example, {4.75, -12, pi, sqrt(5), 29}. It belongs to the set of integers which is a proper subset of rational numbers which is a proper subset of real numbers which is a proper subset of complex numbers. So -12 belongs to all the above sets.

All non-even numbers are odd. All squares of even numbers are even. All squares of odd numbers are odd. Therefore all numbers which are odd and not the square of an odd number are the solution set. It contains: {3, 5, 7, 11, 13, 15, 17, 19, 21, 23, 27, 29, 31, ...}

The set {1, pi, -3.9} is one such set.

The cardinal number of a set is the number of elements in the set. Example: the cardinal number of the set {6, prune, 675, biscuit, London} is 5, since the set contains five elements. If a set contains repeated elements, they should only be counted once. Example: the cardinal number of the set {6, 7, 3, 4, 4, 7} is 4 (not 6) since the fours and sevens are only counted once.

No. Zero is a number, so the "set of zero" contains one element. The empty set, also known as the null set, contains no elements.

The set of all rational numbers.If the set contains all of them then no other set can contain any more rational numbers.

Yes, 15 is a whole number.

It's called an infinite set.
