how do you identify opposite and absolute value of a rational number
The opposite of the absolute value of x is always -abs(x).
It would be a positive or negative number
The opposite of any rational number, q is -q. Then if q >= 0 , its opposite and absolute value are both q.If q < 0 then -q > 0 and the opposite and absolute value are both -q.
Suppose x is a rational number -x is the [additive] opposite of x.If x < 0 then -x > 0 so that the absolute value is -x (if x is negative then -x is positive).if x >= 0 then the absolute value is x.
When the number is 0.
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.
The absolute value is always positive.
An "opposite" is not a well defined term since there are additive opposites and multiplicative opposites and you have not specified which one.The absolute value of a rational number is the value of the number with a positive sign.Thus (abs(5/7) = 5/7and abs(-5/7) = 5/7
It is the number with the same magnitude (absolute value) and the opposite sign.
They are all non-positive rational numbers.

When the number is non-positive.
