Answer

The number is 28. The absolute value of number is 28.

Work Step by Step

Since the opposite of a number $A$ is to put a negative sign in front of the number, if the opposite of number $A=-28$, then, by removing the negative sign from it comes out the original number $A =28$. Since the absolute value of a number $A$ is that number's distance from 0 on the number line, if $A=28$, then $|28|=28$.
