give an example of a number that is a integer, but not a whole number
An example of a number that is an integer but not a whole number is -2.5.
To understand why, let's break down the concepts of integers and whole numbers:
- Integers include all positive and negative whole numbers, as well as zero (0). They do not include fractions or numbers with decimal parts.
- Whole numbers are a subset of integers that include all positive whole numbers (1, 2, 3, ...) and zero (0). They do not include negative whole numbers or numbers with decimal parts.
Given this explanation, -2.5 is an example of an integer because it is a negative number without any decimal places. However, it is not a whole number because it includes a decimal part (-0.5), which makes it a decimal number.
In summary, an example of a number that is an integer but not a whole number is -2.5.
I cannot think of any.
