Answer:
0.514
Step-by-step Explantion:
Denominator = 500 = 2^2 * 5^3
257/500 = 257/2^2*5^3 = 2*257/2*2^2*5^3 = 514/2^3*5^3 = 514/(2*5)^3 = 514/10^3 = 0.514
 
        
             
        
        
        
Answer:
B
Step-by-step explanation:
To find the constant of proportionality between y and x, divide   for all given values of the chart. If you get the same number, then that is the constant. If they are all different numbers, then one does not exist for that function.
 for all given values of the chart. If you get the same number, then that is the constant. If they are all different numbers, then one does not exist for that function.
Using the method above, you should get:
Chart A = 2/5
Chart B = 1/5 (Correct Answer!)
Chart C = N/A
Hope this helps!
