In the set of whole numbers is 4-9 meaningful

In the set of whole numbers, only positive integers are considered meaningful. Therefore, the numbers 4 to 9, inclusive, are indeed meaningful in the set of whole numbers.

To determine the meaning of numbers in the set of whole numbers, you need to understand what whole numbers are. Whole numbers are the set of non-negative integers, which means that they include all positive integers (1, 2, 3, ...) and zero. It does not include any negative numbers or fractions/decimals.

So, when evaluating if a number is meaningful in the set of whole numbers, you simply need to check if it is a positive integer or zero. In the case of 4 to 9, all of these numbers are positive integers and therefore, they are meaningful in the set of whole numbers.
