Is Pi A Rational Number Is Pi A Rational Number
Let us remind the concept of Rational Numbers. Rational numbers are the ratio of two different unified integers. Or in other words, we can say that rational numbers are simply the ratio of two numbers with no common factor in them. Now, any fractional number may be a rational number or may not be, it depends on the nature of the fractional number that is whether the number has finite number after decimal or not. If any fractional number is re-written as the simplified ratio then it is a rational number. Let us discuss about the number pi. Now, if we see the value of it is approx 3.14159265.... That is it has an infinite decimal places as the value of pi is no finite. Since the pi is an infinite number (after decimal) or the value after the decimal is non – terminating (that means the value has no end), therefore the number 3.14159265 cannot be displayed as a ratio of two integers.

Since the value of pi that is also written as ( 22 / 7 ) but this value is not perfect that is it is an approximate value, the actual value of pi is 3.14159265 and it is an non – terminating number, there fore pi is not an rational number. Irrespective of the value of pi that is 22/7 it is not considered as a rational number as the actual value of pi is 3.14159265 which is not a rational number. Therefore the number pi is not a rational number. Divide -243/126 / -81/49? Like addition and subtraction we don’t need to equalize the denominator we can multiply them as, numerator of 1st number *denominator of 2nd number/denominator of 1st number *numerator of 2nd In other words we can say dividing the number is just equivalent to multiplying the 1st number with the reciprocal of other. We also need to see one thing the sign convention that’s also plays a very important role in the division we need to know that in multiplication (+) *(+)= + , multiplication of (-) * (-) =+,multiplication of (-)* (+)= - and multiplication of (+) * (-) = - we can also remember these convention as if we have the same sign then the result will always be positive and if signs are negative then result will always be negative ,I think this is the simplest way to remember the sign convention. What is a Rational Number? The Rational Numbers are those numbers which can either be whole numbers or fractions or decimals. Rational numbers can be written as a ratio of two integers in the form 'p/q' where 'p' and 'q' are integers and 'q' is nonzero. A rational number is simply a ratio of two integers, for example1/5 is a rational number (1 divided by 5, or the ratio of 1 to 5). Read More About Rational Numbers Worksheets Tutorcircle.com

Introduction to Rational numbers Today, I will tell you a story. Once there was a family of Natural numbers where all counting numbers used to live. One day a guest named zero visited the house and requested for a permission to stay there. All were happy; they requested the eldest member of the family Mr. infinite (∞) to grant the permission for 0. Definition of Rational Number In mathematics, Rational Numbers can be defined as a ratio of two integers. Rational numbers can be expressed in form of fraction 'a/b' in which 'a' and 'b' are integers where denominator 'b' not equal to zero. We also have set of rational number and 'Q' is used to represent it. Positive Rational Numbers Positive Rational Numbers can be expressed as the ratio 'p/q' where, 'p' and 'q' are both positive integers. Any positive rational number can be expressed as a sum of distinct reciprocals of positive integers like: 3/5 = 1/3+2/6+1/18.
