A number x is said to be rational if it can be expressed as the ratio p/q where p and q are integers, and q is not 0. For each rational number there is an equivalent decimal representation which is either a terminating decimal or one that has an infinitely recurring pattern. A decimal number which is infinite but without any recurring pattern is an irrational number.
Thus rational numbers form a subset of decimal numbers.

How is the decimal of an irrational number different from the decimal of a rational number?
The difference is that rational numbers stay with the same numbers. Like the decimal 1.247247247247... While an irrational number is continuous but does not keep the same numbers. Like the decimal 1.123456789...
Can difference between two irrational number can results in rational number?
Yes. 2+sqrt(3) and 5+sqrt(3). Their difference is 3, which is rational.
A decimal number is an irrational number?
A decimal number can be rational or irrational.
Is number 1.41421356 a rational or irrational number?
It is a rational number because it is a terminating decimal
Is 3.142857 a rational or an irrational number?
It is a rational number because it can be expressed as a decimal
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
What is the difference between recurring and non recurring decimal?
A recurring decimal is a rational number, a non-recurring one may be rational (for example 0.2 = 1/5) or irrational.
What is the decimal rational number between 3 and 4?
The decimal number midway between 3 and 4 is 3.5
What is the difference between the decimal expansion in irrational and rational numbers?
Decimals that terminate or repeat in some fashion are rational, while decimals that expand forever are irrational.

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.
Is 8.2 a rational number?
Yes. Any terminating decimal is a rational number. Any repeating decimal also.
Must the difference between two rational numbers be a rational number?
Yes.
Must the difference between two rational be a rational number?
Yes, it must.
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?
