The expression \(\frac{5}{a}\) represents a fraction where 5 is the numerator, and \(a\) is the denominator. The value of this expression depends on the value of \(a\).

### Cases to Consider:
1. **If \(a = 0\)**, the expression becomes undefined because division by zero is not allowed.
2. **If \(a > 0\)** or **\(a < 0\)**, the expression is valid and represents a rational number.

Would you like to simplify or evaluate it further based on a specific value of \(a\)?

### Related Questions:
1. What happens to \(\frac{5}{a}\) as \(a\) approaches zero?
2. How does \(\frac{5}{a}\) behave when \(a\) is a negative number?
3. Can you express \(\frac{5}{a}\) in decimal form for specific values of \(a\)?
4. How do we solve equations where \(\frac{5}{a} = b\)?
5. How can \(\frac{5}{a}\) be graphed as a function of \(a\)?

**Tip:** Dividing by a variable means the value of the expression changes inversely with the variable's magnitude.
