pi, e
Irrational Numbers have names because they cannot be written down completely. Pi (as in Pi R squared) and e ( Euler's number, a mathematical constant) are examples of irrational numbers.
Another answer:
Irrational numbers are numbers that cannot be stated as the quotient of two integers. The square root of 2, 1.414..., is an example to an irrational number. Pi and e are transcendental numbers, where they cannot be expressed as the root of algebraic equation having integral coefficients.

Is 10.46 irrational?
it is not irrational. This is because there are two non irrational numbers that divide each other that are rational. So 10.46 is rational.
What are two characteristics of a rational and irrational number?
Rational numbers - can be expressed as a fraction, and can be terminating and repeating decimals. Irrational numbers - can't be turned into fractions, and are non-repeating and non-terminating. (like pi)
What is the differences among integers rational numbers real numbers and irrational numbers?
Integers are whole numbers. They are the counting numbers, 0 and the corresponding negative numbers. Rational numbers are numbers that can be expressed as a ratio of two integers (the second one being non-zero). Irrational numbers are numbers that are not rational numbers. Rational and irrational number together form the set of real numbers.
Are non-terminating decimals rational numbers?
If they are non-terminating and there is a repeating pattern, then they are rational. If they are non-terminating and there is no repeating pattern, as in pi, they are irrational.
Why is 8.3 a rational number?
It terminates. I believe that numbers that are non terminating are irrational. and numbers that can be made into a fraction, terminat, or repeat are rational.
Are irrational numbers rational numbers?
No. Real numbers are divided into two DISJOINT (non-overlapping) sets: rational numbers and irrational numbers. A rational number cannot be irrational, and an irrational number cannot be rational.
Do irrational and rational form a negative number set?
No. Irrational and rational numbers can be non-negative.
Is 10.46 irrational?
it is not irrational. This is because there are two non irrational numbers that divide each other that are rational. So 10.46 is rational.
What are non recurring irrational numbers?
All irrational numbers are non-recurring. If a number is recurring, it is rational. Examples of irrational numbers include the square root of 2, most square roots, most cubic roots, most 4th. roots, etc., pi, e, and most calculations involving irrational numbers.
Why is the product of a non - zero rational number and an irrational number is irrational?
Let q be a non-zero rational and x be an irrational number.Suppose q*x = p where p is rational. Then x = p/q. Then, since the set of rational numbers is closed under division (by non-zero numbers), p/q is rational. But that means that x is rational, which contradicts x being irrational. Therefore the supposition that q*x is rational must be false ie the product of a non-zero rational and an irrational cannot be rational.
Does multiplying rational and irrational numbers lead to an irrational number result?
Yes, but only if the rational number is non-zero.
What happens when a rational number is divided by an irrational number?
When a rational numbers is divided by an irrational number, the answer is irrational for every non-zero rational number.
What is 5 sentences about contrasting rational and irrational numbers?
rational and irrational numbers are two types of real Numbers. all real numbers which are terminating and non terminating but repeating comes in the category of rational numbers. all real numbers which are non terminating and non recurring comes in the category of irrational numbers. rational numbers are expressed in the p/q form where p and q are both integers and q is not equal to 0.the opposite the case is with irrational numbers. they are not expressed in the p/q form
Is 3.76 rational?
yes it is rational if those are the only numbers in the decimal places examples of when a number is irrational if it is a square root of a non-perfect square or a non-repeating never- ending decimal such as pi
What are two characteristics of a rational and irrational number?
Rational numbers - can be expressed as a fraction, and can be terminating and repeating decimals. Irrational numbers - can't be turned into fractions, and are non-repeating and non-terminating. (like pi)
If a number isn't a integer what is it?
It is a non-integer. It can be a rational fraction (in decimal or rational form); it can be an irrational number (including transcendental numbers); it could be a complex number or a quaternion.
What is the differences among integers rational numbers real numbers and irrational numbers?
Integers are whole numbers. They are the counting numbers, 0 and the corresponding negative numbers. Rational numbers are numbers that can be expressed as a ratio of two integers (the second one being non-zero). Irrational numbers are numbers that are not rational numbers. Rational and irrational number together form the set of real numbers.
