Decimal expansion of rational numbers x can be any number since 0 divided by any number is zero. We can also write rational numbers as decimals. We do this by performing a quick division that is dividing the numerator by the denominator.

For instance. In Maths, rational numbers are represented in p/q form where q is not equal to zero. It is one of the most important Maths topics. Any fraction with non-zero denominators is a rational number. Hence, we can say that ‘0’ is also a rational number, as we can represent it in many forms such as 0/1, 0/2, 0/3, etc.

The denominator in a rational number cannot be zero. Expressed as an equation, a rational number is a number. a/b, b≠0. where a and b are both integers. This equation shows that all integers, finite decimals, and repeating decimals are rational numbers.

In other words, most numbers are rational numbers. Rational Numbers. A Rational Number can be made by dividing two integers.

(An integer is a number with no fractional part.) Example: is a rational number because = 3/2 (3 and 2 are both integers) Most numbers we use in everyday life are Rational Numbers. Here are some more examples: Number As a Fraction Rational. 5: 5/1: Yes. They include fractions, decimals, and integers.

Understanding rational numbers is important in understanding and analyzing real-world occurrences, such as changes in barometric pressure during a storm.
