7 bicycles dived by two mopeds = 3.5
$152 x 3.5 = $532
your answer is $532. 
        
             
        
        
        
Disagree, the fractions are unequal and 10/15=66% while 15/20=75%
        
             
        
        
        

remember
(ab)/(cd)=a/c times b/d
also 

split it up with like terms

Answer:
f(x) =  
 is the simplest expression
Step-by-step explanation:
We are given an expression and we are supposed to find the simplest form of the given expression.
The given expression is 
f(x) = ![\sqrt[3]{4x^{2} } \times \sqrt[3]{8x^{7} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B4x%5E%7B2%7D%20%7D%20%5Ctimes%20%5Csqrt%5B3%5D%7B8x%5E%7B7%7D%20%7D)
Since the cube root is common we can multiply the quotient inside the radical sign.
f(x) = ![\sqrt[3]{32x^{(2+7)} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B32x%5E%7B%282%2B7%29%7D%20%7D)
      = ![\sqrt[3]{32x^{9} }](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B32x%5E%7B9%7D%20%7D)
      = 
      = 
f(x) =  
 is the simplest expression
