Actually there are more Irrational Numbers than rational numbers.
Most square roots, cubic roots, etc. are irrational (not rational). For example, the square of any positive integer is either an integer or an irrational number.
The numbers e and pi are both irrational. Most expressions that involve those numbers are also irrational.

What is a rational or irrational number?
real number
Is a real number a rational number?
Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction. Not all real numbers are rational.
Are real numbers rational and irrational?
The set of real numbers is divided into rational and irrational numbers. The two subsets are disjoint and exhaustive. That is to say, there is no real number which is both rational and irrational. Also, any real number must be rational or irrational.
If a number is a real number then is it a rational number?
Not necessarily. All rational numbers are real, not all real numbers are rational.
Is a real number always sometimes or never a rational number?
Sometimes. The number '4' is real and rational. The number 'pi' is real but not rational.
Are there real number that are not rational number?
A real number dosen't have to be a rational number as a real number can be rational or irrational i.e the root of 2 is irrational and real. So is (pi).
Is a decimal a considered a real number and a rational number?
Decimals are real. They can be rational or irrational.
Is -3 a rational number and a real number?
Yes. -3 is both rational and real. -3 is an integer. All integers are rational numbers. All rational numbers are real numbers. Thus -3 is a rational number and a real number.
Can a real number that is not a rational number is a?
A real number which is not a rational number is an irrational number.
Every rational number is a real number?
Yes it is, but not every real number is a rational number
Is 34 and real and rational number?
Yes, 34 is a real and rational number
Which number is an integer a rational number and a real number?
Every integer is also a rational number and a real number.
Is a real number sometimes a rational number?
Infinitely rarely, a real number is also a rational number. (There are an infinite number of rational numbers, but there are a "much bigger infinity" of real numbers.)
What is the relationship of rational numbers and real number?
The set of rational numbers is a subset of the set of real numbers. That means that every rational number is a real number, but not every real number is rational. The square root of 2 is an example of a real number that isn't rational; that is, it can't be expressed as the quotient of two integers.
Is a real number always irrational?
Real numbers can be rational or irrational because they both form the number line.
