You divide the numerator of the fraction by its denominator. You may require long division.
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.
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.

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.
If its a rational number then its decimal equivalent can be expressed as a fraction
