What is the procedure of rounding of a rational number?
Rational numbers are not usually rounded - their decimal equivalents are. So convert a rational into its decimal equivalent and then round it to however many places that you want.
Is decimal a rational number?
It depends. A terminating decimal is a rational number. A decimal which, after a finite number of places, becomes a repeating (or recurrent) decimal is also a rational number. A decimal that is not terminating, nor [eventually] settles into a recurring pattern is not a rational number. Note that the decimal need not become recurring immediately.
What are the difference between decimal in rational and decimal in irrational?
A decimal rational number can be expressed as a fraction A decimal irrational number can not be expressed as a fraction
Why decimal is considered as rational number?
A decimal need not be a rational. A non-terminating, non recurring decimal is an irrational number. Only a terminating decimal or a recurring decimal is rational and that is because such a number can be expressed as a ratio of two integers.
What can you say about the decimal expansion of any rational number?
If its a rational number then its decimal equivalent can be expressed as a fraction
Convert the decimal below into a rational number. 0.1?
0.1 is equivalent to 1/10 which is a rational number
How do you convert a rational number to a terminating decimal?
In most cases, you cannot.
How do you convert a decimal into a rational number?
Set the decimal in the form p/q, where p and q are integers.
What is the procedure of rounding of a rational number?
Rational numbers are not usually rounded - their decimal equivalents are. So convert a rational into its decimal equivalent and then round it to however many places that you want.
What can I do if I get a repeating decimal?
You can round the decimal fraction to a suitable level of accuracy. Alternatively, you can convert the number to a rational fraction.

Is 8.2 a rational number?
Yes. Any terminating decimal is a rational number. Any repeating decimal also.
is 0.313111331 a rational or irrational number?
It is rational. An irrational number is a number that you cannot define by a fraction or a decimal. Since you wrote it as a decimal, it is rational.
Is 0.454545... an irrational number?
No. It is a rational number. Any repeating decimal or terminating decimal is rational.
is 27.5 rational or irrational?
It is rational. An irrational number is a number that you cannot define by a fraction or a decimal. Since you wrote it as a decimal, it is rational.
Is a decimal a considered a real number and a rational number?
Decimals are real. They can be rational or irrational.
Is 7.11 rational or irrational?
A number with a finite number of decimal digits is always rational. (If the number of decimal digits is infinite, the number is rational only if there is a repeating pattern.)
