(C) Let $x$ be the fourth proportional to $0.2, 0.12$ and $0.3$.By the definition of proportion,we have:$0.2 : 0.12 = 0.3 : x$This can be written as:$\frac{0.2}{0.12} = \frac{0.3}{x}$Cross-multiplying to solve for $x$:$0.2 	imes x = 0.3 	imes 0.12$$x = \frac{0.3 	imes 0.12}{0.2}$$x = \frac{0.036}{0.2}$$x = 0.18$Therefore,the fourth proportional is $0.18$.

The fourth proportional to $0.2, 0.12$ and $0.3$ is
