Answer:
Step-by-step explanation:
(7/12) of 840 attended the concert:
(7/12)*(840) = 490 students attended the Spring Concert.
(840 - 490) = 350 did not attend
(350/840) is the fraction of students who did not attend.  This can be reduced to (35/84)
(350/840) = 0.4167 or 41.67% did not attend.  
 
        
             
        
        
        
Answer: 800
Divide 3200 by 4 to get 800.
        
                    
             
        
        
        
.50 x 2 < .20 x 100
1 < 20
50% of 2 is not greater than 20% of 100.
