A rational number is a number that can be expressed as (\(p / q\) ) of two integers, a numerator \(p\) and a non-zero denominator \(q\). Since \(q\) may be equal to \(1\), every integer is a rational number.
Difference between a fraction and a rational number:
A number in the rational form where \(p\) and \(q\) are whole numbers and \(q ≠ 0\) is known as a fraction, whereas a number in the form where \(p\) and \(q\) are integers and \(q ≠ 0\) is known as a rational number.
2. is a rational number but not a fraction because \(-3\) is not a whole number.
1. is a fraction as well as the whole number.
There are different types of fractions:
i) Proper fractions
ii) Improper fractions
iii) Mixed fraction
iv) Unit fraction
