Choice B. x>0 so because the squarroote need being greater than zero 
        
             
        
        
        
I’m pretty sure I know the answers but could you tell me the options for the drop boxes:)
        
             
        
        
        
The easiest way to solve this comparison without any unusual comparisons is to find a common denominator for the two fractions. 
2/5 = 18/45
4/9 = 20/45
Since 20/45 is bigger than 18/45, we know that 4/9 is greater than 2/5
