Problem 40 - Algebra and Trigonometry

Question

Give an example of a rational number that is not an integer.

Step-by-Step Solution

Answer

An example of a rational number that is not an integer is \(1/2\).

Step 1: Define a Rational Number

A rational number is any number that can be expressed as the fraction \(p/q\) of two integers.

Step 2: Select a Fraction

One can select any fraction where the numerator is not a multiple of the denominator, for instance, the fraction \(1/2\). It is important to note that \(1/2\) is a rational number because it can be expressed as the fraction of two integers.

Step 3: Verify it's not an Integer

The number \(1/2\) is not an integer because integers are whole numbers and \(1/2\) is not a whole number.
