Of course not. The square root of 2 is less than 3, and (pi) is less than 4 .

What is the niether a prime nor a composite number?
The number 1 is neither prime nor composite.
Is every natural number is a real number?
Yes, natural numbers are the set of "counting numbers" - integers bigger than zero. Hence they are all real numbers.
Which expression represents an irrational number?
It is not always easy to tell if a number is irrational. If a number can be expressed as a ratio of two integers, then it is rational. If not, it is irrational. So the expression is in the negation: a number than cannot be expressed as a ratio of two integers.
List of rational and irrational numbers?
-- There's an infinite number of rational numbers. -- There's an infinite number of irrational numbers. -- There are more irrational numbers than rational numbers. -- The difference between the number of irrational numbers and the number of rational numbers is infinite.
What is the irrational number closets to 13?
There is no such number. Irrational numbers are infinitely dense. Given any number near 13, there are more irrational numbers between that number and 13 than there are rational numbers in all.
Are irrational numbers prime?
A prime number is a natural number that has no natural number as a factor other than itself or 1. An irrational number is not a natural number, so an irrational number can't be prime.
Are there rational numbers then irrational numbers?
There are infinitely many rational numbers, but there are infinitely more irrational numbers than rational numbers. There are more irrational numbers between 0 and 1 than there are rational numbers period.I was kind of guessing what you were trying to ask, so let me explain some background in case that wasn't quite it. Rational numbers are those that are representable as the ratio of two integers: 2/3, 355/113, 5 (=5/1). Irrational numbers are those that cannot be represented exactly by the ratio of two integers; some familiar irrational numbers are pi and the square root of 2. There are an infinite number of integers, and therefore an infinite number of rational numbers, but the two infinities are of the same order of magnitude (called a countable or listable infinity). The mathematical designation for the kind of infinity that the integers have is called aleph-null. There are also an infinite number of irrational numbers, but it's a "bigger" kind of infinity called C or the "power of the continuum." There's a relationship between aleph-null and a larger infinity called aleph-one. It's not known whether C and aleph-one are the same or not, and if they're not, we don't know which is bigger.
What numbers are irrational integers?
I think fractions are irrational unless you make them rational. Is pi rational? Tough question...I don't really remember anything. It's probably a trick question, but if it's not than maybe a repeating decimal.
What is the number that is neither rational or irrational?
Any real number is either rational or irrational. The rational ones are the ones that can be written in the form a/b where and b are integers and b does not equal 0. The irrational ones are all the other ones. If you expand your domain to include numbers other than the real numbers, like the imaginary numbers for example, there is no definition of "rational" or "irrational" for the non-real numbers. Zero is a rational number since it can be written as 0/1 and both 0 and 1 are integers.
Do irrational numbers contain fewer numbers?
No, the set of irrational numbers has a cardinality that is greater than that for rational numbers. In other words, the number of irrational numbers is of a greater order of infinity than rational numbers.
What are irrational and rational numbers?
Rational numbers are any numbers that can be expressed as a fraction. For example 1/3, 1/2, and 2. Irrational numbers are numbers that can not be expressed as a fraction. Some examples are Pi, the square root of 2, and e. Both rational and irrational numbers are real numbers. Unlike imaginary numbers like the square root of -1.An irrational number is a number that can't be expressed by a fraction having integers in both its numerator and denominator. A rational number can be.Rational and irrational numbers are both subsets of real numbers, together they make up the set of what we call real numbers.If you have trouble remembering which is which, just think of rational numbers as fractions, or numbers that can be written as a/b where a and b are integers. Remember that b can equal 1 so [2 = 2/1]. Therefore all integers, as well as whole and natural numbers are also rational numbers.Irrational numbers are real numbers that are not rational. One way that people describe Irrational is the answer goes on and on forever and does not have a repeating pattern. Two classic examples are Pi (3.14159...), and the base of the natural log e (2.7128...).Rational, when expressed in decimal form, can stop (terminate) at a certain point or it may have a pattern of digits which repeats forever. An example of a rational that repeats is 1/3. Certainly it is written as a/b with a and b both being integers, but its decimal representation is 0.333.... where in this case the dots mean that the (3) repeats forever.There is a hierarchy of numbers and understanding it sometimes helps remember and understand the differences.At the top of the hierarchy are the complex numbers. Next come the real numbers and then then rational numbers. Next comes the integers, then the whole numbers and last the natural numbers.An irrational number is a number that can't be expressed by a fraction having integers in both its numerator and denominator. A rational number can be.
What is the niether a prime nor a composite number?

Is every natural number is a real number?
Yes, natural numbers are the set of "counting numbers" - integers bigger than zero. Hence they are all real numbers.
Are numbers below 0.833 always irrational numbers?
No, numbers less than 0.833 are not always irrational. For instance, 0.2 isn't an irrational number
Who can you tell what is rational and irrational?
A rational number is one that can be expressed as the ratio of two integers, for instance, 1/3, -5/3, 8 (which is equal to 8/1). An irrational number can't be expressed as the ratio of two integers. It has been proven that the square root of 2 (as well as the square root of any positive integer that is not a perfect square) is irrational. Pi and e, two important numbers in mathematics, are also irrational. It has also been proven that there are more irrational than rational numbers.
Is there inifinitely many irrational numbers?
Yes. In fact, the cardinality of irrational numbers is greater than that of rational numbers.
Are there numbers that are rational and irrational?
Irrational numbers are have decimal points that never stop. Like pi. They cannot be expressed as a fraction of two integers.Rational numbers, no matter how ridiculous and long, can be expressed in a fraction of two integers. If they are decimals, they will stop at some point. like 0.47They can't be both. That's a paradox. Unless your math teacher says so because he's probably smarter than me. :).................For rational numbers, think of the word ratio. A rational number can be expressed as the ratio (or fraction) of 2 integers. Irrational means not rational.
