If the whole number is a perfect square, its square root is rational. If not, it's not.
It is not possible to tell. There is no recurring pattern that can be discerned.
It is irrational.
The value that occurs the most number of times.
Please tell me
It is not easy. If the value is rational then you must be able to express the value under the radical sign as p2/q2 where p and q are integers and q is non-zero. If not, then the number is irrational.It is not enough to require that for a rational, the number under the radical must be a perfect square since sqrt(2.25) is rational even though 2.25 is not a perfect square.
When it can be expressed as a fraction
Yes. You can tell because there is a finite number of decimal places. 0.91 = 91/100 which is a rational number.
You probably don't have to inspect that pair too closely.Every integer IS a rational number.
a rational number repeats but terminates.ex:3.333333333. a irrational number doesn't terminate or repeat itself. ex:3.334334433444.

It tells you the value (and sign) of the number.
From least to greatest
You cannot. There is no way to determine if the number has or has not been rounded and so no way to determine if the number is a terminating, repeating or other form of decimal number. Without that information you cannot tell if it is rational.
If you can write the number as a fraction, with integers in the numerator and the denominator, it is rational. In the case of decimal numbers, if the decimal representation terminates (e.g. 2.16), or is periodic (perhaps after some initial digits, like 4.130202020202...), then it is rational. For numbers defined according to some rule, it is not always known whether they are rational or irrational. ILuv You!![; <3 Hope This Helps You!!(:
