Question

what is rational number​

Answer 1

Answer:

In mathematics, a rational number is a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q Since q may be equal to 1, every integer is a rational number. The set of all rational numbers, often referred to as "the rationals", the field of rationals or the field of rational numbers is usually denoted by a boldface Q

The decimal expansion of a rational number always either terminates after a finite number of digits or begins to repeat the same finite sequence of digits over and over. Moreover, any repeating or terminating decimal represents a rational number.

Answer 2

A rational number is any number that can be represented in a fraction, in the form of p/q where q is not 0 and where p and q are integers.

A rational number either has no decimals or if it does it will have a pattern to therefore these decimal numbers are either called terminating or repeating decimals.

A famous irrational number is pi because it cannot be represented as a fraction accurately. Some examples of rational numbers are 1/2, 2/1, -2/1, -1, 3, etc.
