Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Absolute Value
The absolute value of a number is its distance from zero on the number line, regardless of direction. It is denoted by vertical bars, such as |x|. For example, |-14| equals 14, as it represents the distance of -14 from 0.

Properties of Absolute Values
One important property of absolute values is that |a/b| = |a| / |b| for any non-zero b. This means that the absolute value of a quotient is equal to the quotient of the absolute values. This property is essential for simplifying expressions involving absolute values.

Equivalence of Expressions
To determine if two expressions are equivalent, we can simplify both sides and compare their values. In this case, we need to evaluate |-14| / |2| and |-14/2| to see if they yield the same result. Understanding how to manipulate and simplify expressions is crucial for solving such problems.
