This is not response to your question, but it is response to question you should have asked.

First of, these numbers indicate that your camera has 5x zoom (22.5 / 4.5 = 5). Second, considering that size of your camera sensor is roughly 6.2x4.65mm these numbers mean that lens of an analog 35mm film camera (or full frame digital one) that gives same field of viewrange is 25~25-125mm. 

Focal length of 50mm gives "normal" FOV approximate to what you see with your eyes, so finally, numbers from your camera finally mean mean that it goes from half of normal FOV (think of it as 2x zoomed-out) to 2.5x normal when fully zoomed in.
