Question

hello friends​

what is rational and irrational

Answer 1

Answer:

hii

Step-by-step explanation:

Rational numbers are numbers that can be expressed as a fraction or part of a whole number. (examples: -7, 2/3, 3.75) Irrational numbers are numbers that cannot be expressed as a fraction or ratio of two integers. There is no finite way to express them. ( examples: √2, π, e)

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.

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

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.
