Apologies for the confusion. You are correct, option 4 is indeed the correct answer. 9 is an integer but not a whole number.
The correct response is:
- It is both an integer and a whole number.
The correct answer is:
It is both an integer and a whole number.
To understand why this answer is correct, let's break down the definitions of integers and whole numbers:
1. Integers: Integers are the set of whole numbers and their opposites (negative whole numbers). In other words, integers include zero, positive whole numbers, and negative whole numbers.
2. Whole Numbers: Whole numbers are the set of non-negative integers, including zero and positive integers. Whole numbers do not include negative integers.
Now, let's analyze the options:
- "It is both an integer and a whole number": This option is correct because 9 is a positive integer and a positive whole number.
- "It is an integer but not a rational number": This option is incorrect because 9 is both an integer and a rational number. A rational number is any number that can be expressed as a fraction, and 9 can be expressed as 9/1.
- "It is a whole number but not an integer": This option is incorrect because 9 is both a whole number and an integer.
- "It is an integer but not a whole number": This option is incorrect because 9 is both an integer and a whole number.
Therefore, the correct answer is that 9 is both an integer and a whole number.
