If 6 of the 13 books are new, then 7 of them are used. The ratio of new (6) to used (7) is
6:7 or 6/7
Ratio of all books (13) to used books (7) is
13:7 or 13/7
                                
             
                    
              
              
                
                
6 of 13 are new right? so that must mean 7 are used
