3/5 of the officers in Blue Springs have enrolled in the additional traffic detail program. If 24 officers have enrolled in the program, how many officers are employed by Blue Springs PD?

  1. 36 workers
  2. 49 officers
  3. 42 officers
  4. 44 officers
  5. 45 officers
  6. 40 officers
Explanation

Answer: F - 40 officers. Think of this in terms of a ratio: 3 parts of 5 are enrolled in the program. Those 3 parts are equal to 24; therefore, 1 part equals 8. So, the total number of workers is 5x8, or 40.

Key Takeaway: Fractions, percentages, decimals, and ratios are closely related. Understanding how to convert between these different forms will allow you to solve a wide variety of problems quickly and accurately.
