Answer:

Step-by-step explanation:
 
14 times a number x :  14* x = 14x
Quotient of 14 times a number x  an 9 :   
5 less the quotient of 14 times a number x and 9 :

 
        
             
        
        
        
The maximum value it can be would be 100%.  The only times that it could be this high is when there is only a class on the frequency distribution table.  Another way, is that there is only one column variable on the table (& or if there is only one row.)  Any other time is will be less, but the maximum stays 100%.
