Answer 2

Answer:

Rational numbers are the numbers which can be expressed in the form $\frac{p}{q} ,\ q$≠ $0$ . And all the numbers other than rational is irrational numbers .

Step-by-step explanation:

 Rational numbers are the numbers which can be expressed in the form of

$\frac{p}{q},$

where both p and q are integers and  $q$ ≠ $0$ ; if $q=0$  , then the number is not defined in mathematics. When $p=0$ , the rational become zero , and is denoted by Q .

Integers are the set of numbers which include both positive and negative of each natural number and zero , and is denoted by Z.

That is $Z=\{...,-3,-2,-1,0,1,2,3,...\}$

And all the numbers which are not rational is called irrational numbers and is denoted by I .

example : $\sqrt{2} ,\sqrt{3}$   etc.

And , rational numbers and irrational numbers together forms set of all Real numbers.

Hence the answer.
