Hi! 
10. 
This question is basically asking you, 10 is 40% of what number? 
10 × 100 / 40 = 25
Fred must do 25 math problems. 
12. 
Bed & Bath = 40%
Clothing = 0.625 = 62.5% 
Appliances = 20% 
Electronics = 0.25 = 25%
Least to Greatest: Appliances (20%), Electronics (25%), Bed & Bath (40%), Clothing (62.5%).
        
             
        
        
        
10-2 = 8 
2^3 =8
(2x2x2) = 8
