how do you identify opposite and absolute value of a rational number
You would need to divide by -1/2.
If the opposite is meant to be the additive opposite and not the multiplicative opposite, then their sum is zero. The reason is that is what defines an additive opposite!
When the number is non-positive.
No. A rational number is one that may be represented as a simple multiple, or a division. Such as one times seven, or three times seven; OR one divided by seven, or three divided by seven. Or similar.A rational number, if a fraction, when multiplied by the divisor of the fraction, will give a simple whole number. e.g. 7/5, when multiplied by 5 becomes the whole number 7.An irrational number is one that cannot be formed by a simple ratio, or a simple division. e and pi are a couple of common irrational numbers. [irrational demonstrates where the name comes from.]No number can be found which will convert them, by multiplication, into a whole number.

The answer depends on whether you mean an additive opposite or a multiplicative opposite.
When the number is 0.
It is the number with the same magnitude (absolute value) and the opposite sign.
The additive opposite of the rational number q is -q. One of q and -q must be non-negative and that is its absolute value.

They are all non-positive rational numbers.

The opposite of the absolute value of x is always -abs(x).
