As an 8th grader, Describe the relationship between rational numbers and whole numbers. Are all rational numbers also whole numbers? Are all whole numbers also rational numbers? Give examples to support your answer. But, only describe this in a summarized, short and simple form.

Answer 1

Rational numbers are numbers that can be expressed as the ratio of two integers (like fractions), where the denominator is not zero. Examples of rational numbers include 1/2, -3, and 0.5.

Whole numbers are non-negative numbers that do not include fractions or decimals. They are 0, 1, 2, 3, and so on.

Not all rational numbers are whole numbers. For example, 1/2 is a rational number but not a whole number.

All whole numbers are rational numbers. This is because each whole number can be expressed as a fraction with a denominator of 1. For example, the whole number 3 can be written as 3/1, which is a rational number.

So in summary:

• Whole numbers are always rational.
• Not all rational numbers are whole numbers.
