Concept:When a ratio $m : f$ is given, substituting the corresponding values directly into a homogeneous expression cancels the common factor.Explanation:Given $m : f = 16 : 3$.Let $m = 16k$ and $f = 3k$, where $k \neq 0$.Substitute these values into $\frac{3m - 16f}{3m + 16f}$.Numerator: $3(16k) - 16(3k) = 48k - 48k = 0$.Denominator: $3(16k) + 16(3k) = 48k + 48k = 96k$, which is non-zero.Therefore, $\frac{0}{96k} = 0$.The expression simplifies to $0$ irrespective of the value of $k$.Answer:The value is $0$, which corresponds to option C.
