Rational and Irrational Number Identification
Rational and irrational numbers are two broad categories of real numbers. Rational numbers can be expressed as a fraction of two integers, while irrational numbers cannot. Identifying whether a number is rational or irrational is crucial for various mathematical operations and applications.
In this section, we will explore the methods for identifying rational and irrational numbers.
Algorithm for Identifying Rational Numbers
A number is rational if it can be expressed in the form a/b, where a and b are integers and b is not equal to 0. Here’s an algorithm to determine if a number is rational:
- Check if the number can be expressed as a fraction of two integers.
- If it can, the number is rational.
- If it cannot, proceed to the next step.
- Check if the number is a terminating decimal.
- If it is, the number is rational.
- If it is not, the number is irrational.
