A 5/12 roof pitch can also be expressed as 5 over 12 and when you're talking to a roofer, this is the most common way you'll hear it explained because it's easy to say in conversation.
Other ways to express a 5/12 pitch is "5 and 12" or "5:12".
In this pitch, the three is your roof's rise and the twelve is the roof's run.
The roof's incline increases four feet for every 12 feet of horizontal measurement.

Installation & Maintenance Factors
When considering ease of installation and total project cost, roofs with a 5/12 pitch are right in the middle of the road for both factors. This pitch is generally easier and less expensive to than something like an 11 over 12 pitch, which is very steep, but harder to move around on and install than a lower sloped 3/12 roof pitch. Middle of the road for all factors, nothing special to really consider.
Maximizing Attic Space
A 5/12 pitched roof allows for more attic space compared to flatter roofs. The extra space can be used for more than just storing your extra Halloween decorations because the height of the ceiling portion is usually enough for an average adult to stand under. Many homeowners will convert the attic space under a 5:12 roof to a living space, extra bedroom, loft area.
When converting an attic into one of these living spaces, you'll need to keep insulation in mind and may need to get creative depending on the height from the floor to the ceilings. Insulating the attic and maximizing total air flow will prevent dampness and eventual mildew/mold growth and also extend the life of your roof over head.
You'll likely have enough space to add in windows to bring in extra daylight and cool air too, which can help keep the space well vented.
Style & Architecture
The 5/12 roof pitch works well with lots of different building styles. It looks just right on classic houses and on modern ones too. This roof has a gentle slope that's not too flat or too steep, so it makes buildings look nice and balanced. It adds a nice shape to the house without being too much. This kind of roof is good for homes because it makes them look welcoming.
Similar to other medium-sloped roofs, the 5/12 pitch is has the practical benefits of shedding water and snow in a controlled manner-- not too fast and not too slow, where it could stagnate like with a low sloped pitch. Make sure you get a good gutter installation, especially if you live in the Northeast like Massachusetts or Connecticut.
