What is Meant by Rational and Irrational Numbers?
In maths, a number is called a rational number if it can be represented in the form p/q, where p, q are integers and q ≠ 0. A number that cannot be represented in the form p/q where p, q are integers and q ≠ 0 is called an irrational number. Rational and irrational numbers together form real numbers. In other words, a rational number has terminating or non-terminating repeating decimal expansion, whereas an irrational number has a non-terminating non-recurring decimal expansion. A few examples are given below:
Rational numbers: 5/2, 6/10, 4, 37/4, 152.478478.., 177.25, √49 (since √49 = 7), (25)1/2,…
Irrational numbers: √2, √3, √7, π, 369.1475147275…
