How can you tell whether a square root of a whole number is rational or irrational?
If the whole number is a perfect square, its square root is rational. If not, it's not.
Is the number 0.040040004.. rational or irrational number?
It is not possible to tell. There is no recurring pattern that can be discerned.
Is square root of 101 rational or irrational?
It is irrational.
What does mode tell you in data?
The value that occurs the most number of times.
What is the value of 4 in the number 1348567?
Please tell me
How can you tell the value of a radical is not a rational number?
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.
How can you tell a number is an rational number?
When it can be expressed as a fraction
Is 0.91 rational?
Yes. You can tell because there is a finite number of decimal places. 0.91 = 91/100 which is a rational number.
How can you tell the difference between a rational number and an integer?
You probably don't have to inspect that pair too closely.Every integer IS a rational number.
How do you tell if a number is rational or irrational?
a rational number repeats but terminates.ex:3.333333333. a irrational number doesn't terminate or repeat itself. ex:3.334334433444.

It is irrational.
What does a decimal number tell you?
It tells you the value (and sign) of the number.
How can a number's position on a number line tell its value?
From least to greatest
When a number is written in decimal and acirc and 128 and 139 form how do we know if the number is a rational and acirc and 128 and 139 number?
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.
How can you tell that a number 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!
