# Standard Form of a Rational Number

The standard form of a rational number is the Ratio or division of an Integer called the numerator by a positive integer called denominator and can be written in form of (numerator/ denominator) or a/b, where a is any integer and b is a denominator with positive integer (denominator is not equal to zero,b≠0). Let’s take some example to understand Rational Numbers, 7/9, 3/5, 25/47 and so on. From these examples it is clear that denominator is positive integer and not equal to zero for the standard form of a rational number.

## Reduce -42 / 30 to the standard form?

Divide the numerator and denominator both by 6 then we will get the standard form as -7/5.
