Question

Define rational number & irrational number. ​

Answer 1

Answer:

RATIONAL NUMBER = a rational number is a type of real numbers, which is in the form of p/q where q is not equal to zero. Any fraction with non-zero denominators is a rational number. Some of the examples of rational number are 1/2, 1/5, 3/4, and so on. The number “0” is also a rational number, as we can represent it in many forms such as 0/1, 0/2, 0/3, etc. But, 1/0, 2/0, 3/0, etc. are not rational, since they give us infinite values.

IRRATIONAL NUMBER = Irrational numbers are the real numbers that cannot be represented as a simple fraction. It cannot be expressed in the form of a ratio, such as p/q, where p and q are integers, q≠0. It is a contradiction of rational numbers.

Answer 2

• The which can be Represented as a fraction in p/q form or in decimal form is called Rational number .
• The number which cannot be represented in p/q and can only be presented as whole number and negative number is called Irrational number .
