Answer:
1/12
Step-by-step explanation:
Given that 
30/360 to lowest fraction equivalent
 Now, we can write 30 as 3×10 
Also, we can write 360 as 36×10
Then, we have
(3×10)/(36×10)
Then, 10 cancel 10, we are left with 
3/36
Also we can write 36 as 12×3
Then, we have
3/(12×3)
Also, 3 cancel 3, we are left with 
1/12
Then the lowest fraction is 1 / 12
1/12
 
        
                    
             
        
        
        
I'm assuming that y2 means y^2 or y squared. In that case, your factors will be (6y+1) and (6y-1). 
        
                    
             
        
        
        
Do cross multiply or butterfly.  
For example first one.
18/x=6/10  So cross multiply  18×10 =6x
180=6x
Divide both sides by 6 to get x alone
180÷6=30
So x =30  Do the same to rest
 
        
             
        
        
        
<span>C would be correct. Statistics and measures taken from raw data help the researcher understand whether or not they have a hypothesis that has held up under testing. Continual support for the hypothesis (and others of the like) can move the concept closer to the category of "theory" or "law," the gold standard in science research.</span>
