I assume you mean a set that contains a single whole number. Yes, you can have sets with zero elements, one element, two elements, etc.; so a set which contains a single number is perfectly valid.
False
Yes, the collection of whole numbers is an example of a set. In mathematics, a set is a well-defined collection of distinct objects, which can be numbers, symbols, or other entities. The set of whole numbers typically includes 0, 1, 2, 3, and so on, extending infinitely. This set can be denoted as {0, 1, 2, 3, ...}.
It is the maximum of that set.
No, the set of natural numbers is a proper subset of the set of whole numbers.
The is false. "the whole number" is a single number while "the set of natural numbers" is a set. A single number cannot be equal to a set.
Yes it is.
set
False
0 is the only number which is in the set of whole number but not in the natural number
null set, cardinality set
It is the maximum of that set.
No, the set of natural numbers is a proper subset of the set of whole numbers.
The is false. "the whole number" is a single number while "the set of natural numbers" is a set. A single number cannot be equal to a set.
The set of rational numbers is the union of the set of fractional numbers and the set of whole numbers.
Yes, 15 is a whole number.
Yes. It has a logical definition and no members violate that definition.
It is a proper fraction.
