Answer:
The solution set to the absolute value is:
or 
Negative real numbers are not included in the solution set, as for 
, 
.
Step-by-step explanation:
From Mathematics, we know that absolute values are defined by the following characteristics:
1) For 
, 
2) For ,
Then, if , then the solution set to the absolute value is:
or
Negative real numbers are not included in the solution set, as for , .
Analysis:{because the number of rulers is exactly three scales}
so a scale represents a number of

A rational number is<em> a number which can be written a ratio of two integers</em>.
In decimal form, a rational number is any number which either <em>terminates </em>or <em>repeats</em> after the decimal point. Since -1.987 terminates after the 7, it <em>is</em> a rational number.
