Step-by-step explanation:
 
        
             
        
        
        
For this case we can make the following rule of three:
 21 ------> 70%
 x --------> 100%
 Clearing x we have:
 x = (100/70) * (21)
 Rewriting we have:
 x = (10/7) * (21)
 x = 30
 Thus,
 21 is 70% of 30
 Answer:
 21 is 70% of 30
