Question

Which of the following statements is always true?

A. All rational numbers are integers.
B. Some whole numbers are not rational numbers.
C. All integers are whole numbers.
D. All whole numbers are integers.

Answer 1

The correct statement that is always true is D. All whole numbers are integers.

Step-by-step explanation:

The correct statement that is always true is D. All whole numbers are integers.

An integer is any positive or negative whole number or zero, while a whole number is any positive whole number or zero. Therefore, every whole number is also an integer, but not every integer is a whole number.

For example, the number 5 is a whole number because it is a positive whole number, and it is also an integer because it is a positive number. However, the number -3 is an integer because it is a negative number, but it is not a whole number because it is not a positive number.

Therefore, option D is the correct statement because all whole numbers are indeed integers.
