The given ratio is:

\[
\frac{27}{329} = \frac{28}{?}
\]

To solve for the unknown value (denote it as \( x \)), we can cross-multiply:

\[
27 \times x = 28 \times 329
\]

First, calculate \( 28 \times 329 \):

\[
28 \times 329 = 9212
\]

Now, divide both sides by 27:

\[
x = \frac{9212}{27} \approx 341.19
\]

So, the value of \( x \) is approximately **341.19**.
