If the two numbers are both whole numbers then yes
It depends, many people do count 0 as a natural number, but MOST do not. So for most HS text book, the answer is NO, all whole numbers are not natural numbers and the reason is 0 is a whole number but not a natural number.
Yes all counting numbers are whole numbers, but the reverse is not true (zero!)
True.
No. It IS true that every whole number is either prime or composite. But there are numbers that are not whole numbers, such as 2.5, which are neither prime nor composite.
Yes, that is true.
That's a little redundant, since all factors are whole numbers. Factors are the numbers that multiply together to get a product. In the sentence 4 x 3 = 12, 4 and 3 are factors of 12; two whole number factors of 12.
That depends - unfortunately, "whole number" is ambiguous, and can mean different things to different people. If by "whole number" you mean "natural number", then both are of course the same. If you choose to include negative numbers in your definition of "whole number", i.e., whole numbers = integers, then the two sets are not the same, and the proposed statement is false.
True
50 and 30
No, the statement is not necessarily true.
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.
An integer is any whole number, so the answer would be true.
