One use is showing how much of something is left. For example, "15/20 boxes remaining" means that there are 15 boxes remaining out of a total 20 boxes.

The slash (/) is also known as: forward slash, stroke, oblique. A slash is often used to indicate "or": Dear Sir/Madam (Sir or Madam)

It is also used in mathematics and coding, commonly to indicate numerical division. It is also used to delineate members of a hierarchical path to locate a file or resource. Note that some computer systems use the backslash for the same purpose.
