Any number that can't be expressed as a fraction is irrational
It is proven that between two irrational numbers there's an irrational number. There's no method, you just know you can find the number.
Surds are normally irrational numbers.
They are irrational numbers!
They are numbers that are infinite
yes * * * * * No. Rational and irrational numbers are two DISJOINT subsets of the real numbers. That is, no rational number is irrational and no irrational is rational.
properties of irrational numbers
the numbers between 0 and 1 is 0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,0.10.
Yes, no irrational numbers are whole numbers.
No. Irrational numbers are real numbers, therefore it is not imaginary.
Not necessarily. The sum of two irrational numbers can be rational or irrational.
Irrational numbers are not closed under any of the fundamental operations. You can always find cases where you add two irrational numbers (for example), and get a rational result. On the other hand, the set of real numbers (which includes both rational and irrational numbers) is closed under addition, subtraction, and multiplication - and if you exclude the zero, under division.
No, but the majority of real numbers are irrational. The set of real numbers is made up from the disjoint subsets of rational numbers and irrational numbers.
