Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Question ###
what is the least density (per km ) when the rank is 5 and the Area (km ) is less than 125,755?

SELECT MIN(density__per_km²_) FROM table_name_77 WHERE rank = "5" AND area__km²_ < 125 OFFSET 755
