Identify the given definition

The problem asks us to identify a specific set of numbers. We are given the mathematical definition:
The set of numbers in the form \(\frac{a}{b}\), where \(a\) and \(b\) are integers and \(b
eq 0\).

Analyze the options

Using the Number Systems and Integers knowledge points, let's evaluate the given choices:

  • real: Real numbers include all rational and irrational numbers. This definition is too specific to represent all real numbers.
  • irrational: Irrational numbers cannot be written in the form \(\frac{a}{b}\) where \(a\) and \(b\) are integers.
  • whole: Whole numbers are non-negative integers \(\{0, 1, 2, 3, \dots\}\), which do not generally require a fractional representation with a non-zero denominator.
  • rational: By definition, any number that can be expressed as the quotient or fraction \(\frac{a}{b}\) of two integers, a numerator \(a\) and a non-zero denominator \(b\), is a rational number.

Select the correct term

The definition perfectly matches the mathematical definition of rational numbers. Therefore, the blank should be filled with "rational".
