This problem can be solved in < than 20 seconds, if you aware of the fact that (0.625) = 5/8 or 62.5%
Since one more 0 is present before 6, multiply the denominator, 8, by 10. 5/80 = 1/16
Ans is (C).

\(0.0625 = \frac{625}{10000} = \frac{25 * 25}{100 * 100} = \frac{1}{4*4} = \frac{1}{16}\) Answer = C One more method (rather interesting)0.0625 is a perfect square of 0.25 Its simplification would also yield a perfect square Only \(\frac{1}{16}\) fits in (Its perfect square of \(\frac{1}{4}\)) Answer = C

Another way of doing this
625 is square of 25.. Hence 0.0625= (25*25)/(100*100)= 1/16..

I think kinjiGC gave the smartest solution here, which is why I gave him some kudos!
I did reach the same in 2 ways, by saying that 0.0625 = 625*10^4, which obviously is 625/10000.
However, as I am not quick with numbers, didn't know that 10000/625 is 16... And, I didn't think of dividing by 625 anyway base on the answer options.
So, as the divisions were easy, I just started doing them from B on. I found it quite quickly, but hat's off to kinjiGC!!!
