Rational and irrational numbers calculator is a handy tool to detect the type of a number. It is designed to tell you whether the inputted number is rational or irrational.
You can enter numbers in two forms: fraction and decimal since only these types are confusing. It solves the value into decimal form, this means it can also be used as a rational expression/equation calculator.
Follow the instructions below to use this calculator.
Rational and irrational are the basic types of mathematical numbers. Both of these are defined below.
“Such numbers which you can express in the form of a fraction where the denominator is not zero”
For example 3, 1/9, √4 e.t.c. All of these values are rational because;
All integers, perfect squares, and whole numbers are rational. A property of rational numbers is that either they are finite (stops like 2.457) or infinite and repeating (1.333… ).
It is the opposite of rational numbers.
“Such numbers which you cannot express in the form of a fraction”
For instance the famous number pi (π) and Euler’s number e. Irrational numbers are infinite and non-repeating.
You can use the rational and irrational number checker to identify any number.
There are a few tricks that can help to identify the nature of a number manually.
Identify the following numbers as rational or irrational. Also, explain the reason.
First number: Rational
Reason: It is infinite recurring (repeating).
Second number: Rational
Reason: It is in p/q form.
Third number: Irrational
Reason: It is infinite but non-recurring.
Last number: Rational
Reason: It is a perfect root.
