Question

Give an example of a number that is an integer, a whole number, and a natural number.

Step-by-Step Solution

Answer

1

Step 1: Understanding Integer

An integer is a number that can be written without a fractional or decimal component. It includes positive and negative numbers and zero. For example, -2, -1, 0, 1, 2 are all integers.

Step 2: Understanding Whole Number

Whole numbers are a set of numbers that include zero and all the positive integers. They do not include any negative numbers or fractions or decimals. So, 0, 1, 2 are all examples of whole numbers.

Step 3: Understanding Natural Number

Natural numbers are all positive integers excluding zero. They are the numbers we use to count objects. So, 1, 2, 3, are all natural numbers.

Step 4: Find a common number

From the understanding of each category, we need to find a number that is an integer, a whole number, and a natural number. From the examples given above, '1' is a number that fits in all three categories. Therefore, '1' is a number that is an integer, a whole number, and a natural number.
