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 different types of numbers

Remember that an integer is a number that can be written without a fractional or decimal component. It includes positive, negative, and zero. A whole number is always non-negative and can be either zero or positive. A natural number is always positive and does not include zero. Therefore to find a number which is an integer, whole number, and natural number at the same time, it should be positive.

Step 2: Identify a number that fits all categories

Choose a positive number greater than zero. Any positive number greater than zero will fit in all three categories i.e., integers, whole numbers, and natural numbers. For instance, 1 is a suitable choice.
