Integers a and b are consecutive multiples of 6. Integers x and y are consecutive multiples of 8. In terms of a, b, x, and y, what is the ratio of the average of a and b and the average of x and y?
A. \(\dfrac{(x+y)}{(a+b)}\)
B. \(\dfrac{(a+b)}{(x+y)}\)
C. \(\dfrac{\left(a+\dfrac{b}{4}\right)}{\left(y-\dfrac{x}{4}\right)}\)
D. \(\dfrac{\left(a+\dfrac{b}{4}\right)}{\left(y-\dfrac{x}{2}\right)}\)
E. \(\dfrac{1}{2}\dfrac{(a+b)}{(x+y)}\)
The OA is B
