How do you identify the opposite and the absolute values of a rational numbers?

Answer 1

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) = 5/7

and abs(-5/7) = 5/7

Answer 2

It would be a positive or negative number

Answer 3

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.

Answer 4

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.
