Is 12.05 a rational number or irrational number?
1.96 is a rational number
There is no such thing as a number that is both rational and irrational. By definition, every number is either rational or irrational.
The number 82 is a rational number because it can be expressed as a fraction, specifically ( \frac{82}{1} ). Rational numbers are defined as numbers that can be written as the quotient of two integers, where the denominator is not zero. Since 82 meets this criterion, it is classified as rational.
No.
yes, 82 is rational. Rational numbers are numbers that can be written as a fraction. Irrational numbers cannot be expressed as a fraction.
Actually, as a non-integer square root of a number, 82 is an irrational number. It has no end.

82 is an integer and not a fraction. It therefore makes little, if any, sense to write it as a mixed number. However, if you must, it can be expressed in rational form as 82/1.

Is 12.05 a rational number or irrational number?
Sure. Let's take an example with numbers instead of variables. 8/9 is a rational number - the ratio of two integers. If you square it, you get (8/9)2 = 82/92 = 64/81; that is, if you square each integer, you get an integer again. Therefore, the resulting number is rational again - a number that can be expressed as the ratio of two integers. Replace with any other integers; you will still have a ratio of integers if you square it.
