It is easier to answer the opposite: an irrational number cannot be written as:
It can be written as an expression containing Irrational Numbers, such as 2*pi or 3*√2 or sin(37°) or log(3) or e2 or a combination of these or similar functions.
Not completely to its end. If you can completely write a number with digits, then it's a rational number.
5.39 is the ratio of 539 to 100 ... completely rational.Any number that you can completely write down with digits is rational.
The sum of a rational and irrational number must be an irrational number.
rational * irrational = irrational.
No, 3.56 is not an irrational number. 3.56 is rational.
sqrt(2) + sqrt(3) is irrational.
Not completely to its end. If you can completely write a number with digits, then it's a rational number.
Any irrational number can be approximated by decimals. You can never write it exactly, since there are an infinite number of decimals, and these don't repeat.
Being rational or irrational is not about "predicting the next digit"; the definition of a rational number is that you can write it as a fraction, with integer numerator and denominator.Being rational or irrational is not about "predicting the next digit"; the definition of a rational number is that you can write it as a fraction, with integer numerator and denominator.Being rational or irrational is not about "predicting the next digit"; the definition of a rational number is that you can write it as a fraction, with integer numerator and denominator.Being rational or irrational is not about "predicting the next digit"; the definition of a rational number is that you can write it as a fraction, with integer numerator and denominator.
NO it is not irrational, that is to say it IS rational. If you can write a number as ratio of integers, it is rational. -11.7 can certainly be written as a ratio of integers.
Rational
No. Quite simply an irrational number cannot be written as a fraction and you could write zero as a fraction ex. 0/1

its with numbers
No, 3.14 is not an irrational number.
No. If you can write the number on paper, it's rational. 68 is the ratio of 68 to 1.
An irrational number.
