The solution of the equation $\frac{x}{17}=\frac{14.6}{38.5}$ is $x=6.45$.
\begin{align} & \frac{x}{17}=\frac{14.6}{38.5} \\ & x=\frac{14.6}{38.5}\left( 17 \right) \\ & x=6.446 \end{align} Since the thousandth digit is greater than $5$, the hundredth digit will be raised by $1$. Therefore, the solution up to three significant digits will be $x=6.45$.
