what is the rule in adding rational numbers
The value of the answer is the sum of the absolute values of the numbers and the sign of the answer is the same as that of the two numbers.
Then you are adding two rational numbers with different signs! No big deal!
Adding and subtracting integers is a specific case of adding and subtracting rational numbers, as integers can be expressed as rational numbers with a denominator of 1. The fundamental rules for adding and subtracting integers—such as combining like signs and using the number line—apply similarly to other rational numbers, which can include fractions and decimals. The operations are governed by the same principles of arithmetic, ensuring that the properties of addition and subtraction, such as commutativity and associativity, hold true across both integers and broader rational numbers. Thus, mastering integer operations provides a solid foundation for working with all rational numbers.

Subtraction is not commutative nor associative.

Wats are temples from South East Asia and, as far as I am aware, they do not dicatate any rules for adding rational numbers.

The set of rational numbers includes all whole numbers, so SOME rational numbers will also be whole number. But not all rational numbers are whole numbers. So, as a rule, no, rational numbers are not whole numbers.

No
sometimes true (when the rational numbers are the same)
Subtraction is not commutative nor associative.
A rational number can be stated in the form a/b where and b are integers. Adding or multiplying such numbers always gives another number that can be expressed in this form also. So it is also rational.
Never.
There is only one type of rational number so there are no different types which you can add.
