Chapter 1, Problem 55

Evaluate each expression. See Example 5. |3⁄2|

Verified step by step guidance
1
Recognize that the expression involves the absolute value function, denoted by vertical bars \(| \cdot |\), which returns the non-negative value of the number inside.
Identify the number inside the absolute value: \(\frac{3}{2}\).
Recall that the absolute value of a positive number is the number itself, so \(| \frac{3}{2} | = \frac{3}{2}\).
Express the final answer as a positive fraction or decimal, depending on the context of the problem.
No further simplification is needed since \(\frac{3}{2}\) is already in simplest form.

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 represents its distance from zero on the number line, regardless of direction. It is always non-negative. For example, |3/2| equals 3/2 because 3/2 is positive, while |-3/2| would also equal 3/2.
