Answer:
B
Step-by-step explanation:
Multiply each ratio by the same number
4x3=12 7x3=21
 
        
                    
             
        
        
        
So first you would evaluate the power making the 4^3=64 then keep the rest of the problem the same.... then add the numbers 64+8 since their the whole numbers and that would equal 72 so now the problem should be 72-9/y. After that you write all the numerators above the common denominator making the final answer to be 72y-9/y
        
             
        
        
        
1/5 divided by 5/7 is 7/25
1/5 ÷ 7/5 = 7/25
Your answer is 7/25
