Also, what would you like to use for a proof? Analysis? Topology?
Irrational numbers are numbers that cannot be written as a ratio of two integers. They are numbers that cannot be expressed as terminating or repeating decimals.
Rational numbers are numbers that can be expressed as a ratio of two integers. They can be written as terminating or repeating decimals.
This can be proven using the theorem called the "density of rational numbers". This theorem states that between any two irrational numbers, there exists an infinite number of rational numbers.
There is no specific method to find a rational number between two irrational numbers. However, by using the density of rational numbers theorem, we can always find a rational number between any two irrational numbers.
This proof is important because it helps us understand the relationship between irrational and rational numbers. It also shows that these two types of numbers are not completely separate, but rather, they are interconnected and can be used to describe the same quantities in different ways.
