To determine the ratio (r) of people to books, simply divide the number of people (P) to the number of books (B). This is shown in the equation below.
 
                                             r = P / B 

Substituting the given values,
 
                                       r = 50 people / 4,000 books
                                           r = 1 / 80

Thus, the ratio of people to books is 1:80.
