### Example Question #10 : How To Find The Solution To An Inequality With Multiplication

Which of the following numbers could be a solution to the inequality ?

**Possible Answers:**

**Correct answer:**

In order for a negative multiple to be greater than a number and a positive multiple to be less than that number, that number must be negative itself. -4 is the only negative number available, and thus the correct answer.
