We can see that,
0.16667 = 1/6 , 0.3333 = 1/3 , 0.2222 = 2/9, 0.6667 = 2/3 , 0.125 = 1/8 , 0.8333 = 5/6
Side note: If one does not remember, quick way to find these out would be as follows: Let x = 0.22222, 10*x = 2.22222, so 10*x - x = 2
Hence 9x = 2, or x = 2/9
If we substitute back we get 2.5 as the answer.
Hope that helps.

0.16667 = 1/6
0.3333 = 1/3
0.2222 = 2/9
0.6667 = 2/3
0.125 = 1/8
0.8333 = 5/6
Substituting this,
9*3*8*5/6*3*6*2*2 = 5/2 = 2.5
D is the answer.
