1. -1/5>-3/5 because we have like denominators we compare the inputs by the numerators.
2. 3/4 > 5/8 the least common denominator is: 8
Rewriting as equivalent fractions with the LCD: 
                                    3/4 = 6/8    5/8 = 5/8
Comparing the numerators of the equivalent fractions we have: 
                                    6/8 > 5/8   
 
        
             
        
        
        
Divide the restocking fee by the price of the item:
12/200 = 0.06
9/150 = 0.06
Multiply by 100 to get the percent:
0.06 x 100 = 6%
Answer: 6%
 
        
             
        
        
        
12/50=24% of student bring lunch so 24%-524=398 student buy lunch out of 524
