Is pi divided by e rational?
A rational number is able to be represented as a ratio of polynomials. pi/e is a ratio of irrational numbers, neither of which can be represented as a ratio of polynomials, and so I would conclude that pi/e is not rational. But it's a good question, because what if two irrational numbers could cancel out their irrationality, like two negative numbers! A quotient of two irrational numbers can be a rational number. Trivial example 2pi/pi = 2.
Are rational numbers closed under multiplication?
Rational numbers are closed under multiplication, because if you multiply any rational number you will get a pattern. Rational numbers also have a pattern or terminatge, which is good to keep in mind.
What is a good definition of irrational numbers?
A real number that can not be expressed as a rational number.
Which are the numbers of rational numbers?
There are an infinite number of rational numbers.Rational numbers are any number that can be expressed as a ration between 2 other numbers. 2 for example is a ratio of 2/1, 10000 = 10000/1, a half or 0.5 = 1/2 a third or 0.3333333333333reaccuring = 1/3 etc. Irrational numbers are those numbers than cannot be expressed no matter how hard we try to by dividing 2 numbers. Good examples of irrational numbers is square root of 2 (gives us 2 irrational numbers) and the ratio of a circles circumference to its diameter otherwise better known as pi (3.14159265etc,etc,etc). It is from this that we get the word irrational meaning beyond common sense.
Is 0.727272 a rational number irrational number both irrational and rational or neither?
Oh honey, 0.727272 is a rational number. It can be written as 8/11, which is a nice, tidy fraction. So, it's not irrational, not both, and definitely not neither. Just a good ol' rational number, nothing fancy.
Is 3.625 rational or irrational?
Oh honey, 3.625 is as rational as a person who brings a calculator to a math test. It's a decimal number that can be expressed as a fraction, making it a rational number. So, go ahead and embrace that rationality, you're in good company.
How did Babylonians use rational numbers?
They used the sexadecimal system which has 60 digit base. It was good for keeping track of time.
How whole numbers integers rational numbers and irrational numbers came?
When pre-historical people started counting - their friends (or members in their "gang"), their enemies, the numbers of prey animals or how many days away there was water or good hunting - they counted in integers. That was fine until they needed to share things. And that is when ratios or rational numbers came in. However, once they started studying mathematics - geometry in particular - they found that some problems could not be solved using rational numbers. For example, if you had a square with unit sides, its diagonal could not be rational. A circle with unit radius did not have a unit circumference. Irrational numbers were introduced to deal with this shortcoming.
Is the number 23 an irrational number or a rational number?
Rational.All counting numbers (1, 2, 3 etc.) are rational. In fact many fractions/decimals are rational too. Rational just means that we know when the numbers stop.A good example of an irrational number is Pi, which equals 3.14159265358979.... and it just keeps going. No one knows the exact number of pi because as far as anyone can tell, the numbers keep going forever without any proper repeating pattern.
