When multiplying a rational number, it is not necessary that the resulting number is always irrational π × π = π 2 is irrational But √2 × √2 = 2 is rational Sum of Two Irrational Numbers The answer to this is also similar to the above property The Sum of two irrational numbers is sometimes rational sometimes irrational7 2 2 is a rational number Since we know that the difference between a rational and an irrational number is always an irrational number So, ( π − 7 2 2 ) is an irrational number Example π (Pi) is a famous irrational number We cannot write down a simple fraction that equals Pi The popular approximation of 22/7 = is close but not accurate Another clue is that the decimal goes on forever without repeating

π-22/7 is rational or irrational or zero
π-22/7 is rational or irrational or zero-A rational number is a number that is expressed as the ratio of two integers, where the denominator should not be equal to zero, whereas an irrational number cannot be expressed in the form of fractions Rational numbers are terminating decimals but irrational numbers are nonterminating Pi is an irrational numberπ is an irrational number 22/7 is a rational number as is defined a ratio of 2 integers (nonzero denominator) Many people confuse π with 22/7 We are taught in schools that π=22/7 What they should actually teach is π≈22/7 π is irrational It cannot be represented as a ratio of 2 integers(with non zero denominator)

A number which cannot be written in the form p / q where p and q are integers and q is not equal to 0, is called an irrational number An irrational number is nonterminating and nonrepeating, meaning it doesn't have an ending like 075 or , and it doesn't have a set of decimal numbers repeating again and again For example, take 22 / 722/7 is a rational number All rational numbers can be expressed as a fraction whose denominator is non zero Whereas, pi cannot be expressed in the fraction of two integers and has no accurate decimal value, so pi is an irrational number22/7 is a rational number as is defined a ratio of 2 integers (nonzero denominator) Many people confuse π with 22/7 We are taught in schools that π=22/7 What they should actually teach is π≈22/7 π is irrational It cannot be represented as a ratio of 2 integers (with non zero
1 Answer1 Active Oldest Votes 14 My guess is that you are thinking of the approximation 22 / 7 ≈ π The two numbers π and 22 / 7 are not equal, so there's no contradiction in one being rational and the other irrational Sometimes you use 22 / 7 π is written in the form of 22/7 then why is it an irrational numberπ is the ratio between circumference and diameter , one of them either circumference or diameter is an irrational number,so π is called an irrational number,the value 22/7 of π we use in the calculation is actually the nearest rational value of π,therefore 22/7 is a rational number but π is an irrationalAs you know the definition of rational number is any number that can be represented as p/q where p and q are integer and q is not equal to zero And here 22 and 7 both are integer So it is a rational no now the confusion will be that Pi (π) is equal to 22/7 then why Pi is irrational and 22/7 is rational

22/7 is a rational number All rational numbers can be expressed as a fraction whose denominator is non zero Whereas, pi cannot be expressed in the fraction of two integers and has no accurate decimal value, so pi is an irrational number Subsequently, question is, why is 2 pi irrational?But √2 × √2 = 2 is rational; In fact, it won't be either rational or irrational Because any nonzero number divided by zero is undefined Which means we don't get any real value solution at all And therefore, any fraction with a zero denominator won't fall under the category of either rational or irrational numbers 22/7 Is One Of The Most Famous Rational Number

Answer choices A rational number is a number that has a 2 A rational number is a number that can be written as a fraction Pi (π) is an irrational number as it is nonterminating and nonrepeating in nature However, in mathematics, in order to make calculations easier, pi is rounded off as 314 and is also represented in fraction form as 22/7 Question 2 Which of There are four major steps in Niven's proof that π is irrational The steps are 1 Assume π is rational, π = a/b for a and b relatively prime 2 Create a function f(x) that depends on constants a and b 3 After much work, prove that integral of f(x) sin(x) evaluated from 0 to π must be an integer, if π is rational 4
