What is the fastest way to solve this?

a) 4
b) 5
c) 6
d) 7
e) 8
I would like to use approximation of numbers as below:
\(\frac{(0.513)(0.488)(0.942)}{(0.684)(0.314)(0.183)}\)
=\(\frac{(513)(488)(942)}{(684)(314)(183)}\)
apx=\(\frac{(500)(500)(950)}{(700)(300)(190)}\)
apx=\(\frac{(5)(5)(5)}{(7)(3)}\)
apx=\(\frac{(5)(5)(5)}{(7)(3)}\)
apx=\(\frac{(125)}{(21)}\)
apx=6....................(21*6=126)................................Thus
Answer c
