\(\frac{(0.513)(0.488)(0.942)}{(0.684)(0.314)(0.183)}\) \(=\) \(\frac{(3*0,171)(8*0,061)(3*0,314)}{(4*0,171)(0.314)(3*0,061)}\) \(=\) 6

Answer: C

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

Take approximate values and solve

0.5*0.5*1/(0.7*0.3*0.2)
=125/21
Approx 6
as 21*6=216
