Question: 1 / 400

Which of the following includes both integers and fractions?

Rational numbers

Rational numbers encompass both integers and fractions, making them the correct choice. By definition, rational numbers are those that can be expressed as the quotient or fraction of two integers, where the denominator is not zero. This means that any integer can be represented as a fraction by using 1 as the denominator (for example, the integer 3 can be expressed as 3/1). Additionally, all fractions, such as 1/2 or -3/4, are also included in the set of rational numbers. Thus, rational numbers form a comprehensive category that includes all integers and fractions.

In contrast, whole numbers consist merely of non-negative integers (0, 1, 2, etc.), excluding negative integers and fractions. Even numbers and odd numbers are classifications of integers based on their divisibility by 2 and do not include any fractions or non-integer values.
