An example of a number that is a rational number, an integer and a real number would be 2.
1Step 1: Rational Number
Choose an integer, for example, 2. It can be written as a fraction as \( \frac{2}{1} \), so it is a rational number.
2Step 2: Integer
The number 2 is a whole number, without a decimal or fraction attached, which makes it an integer.
