Irrational numbers are also real numbers: those are decimals that are nonterminating like π and √2.
These are rational numbers, which are also real numbers. Decimals can be rational as well - they're just numbers that have either terminating or repeating decimals. This can include whole numbers or integers, fractions, rational numbers and irrational numbers. We have seen that all counting numbers are whole numbers, all whole numbers are integers, and all integers are rational numbers. Rational numbers are numbers that can be written as a fraction, which includes whole numbers, all of which can be written as a fraction: 3/8, 5/1, 9/10, etc. Real numbers are, in fact, pretty much any number that you can think of. Real numbers can also be described as all the numbers that are either rational or irrational. So, even though the number after the decimal never ends, they can still be plotted on the number line.

Strangely enough, numbers such as √2 (the square root of 2, the value of which is 1.14142.) and π (3.1415.) can be plotted on a number line as well, even though they are nonterminating decimal numbers. Free Rational Number Calculator - Identify whether a number is rational or irrational step. Real numbers consist of all the rational as well as irrational numbers. The numbers 27, -198.3, 0, 32/9 and 5 billion are all real numbers.
Any number that can be plotted on this number line is a real number. Real numbers are based on the concept on the number line: the positive numbers sitting to the right of zero, and the negative numbers sitting to the left of zero. Real numbers are basically all the numbers you could think of if somebody told you to think of a number.
