39‚1:x=18‚63:46,5

To solve the proportion \( \frac{39.1}{x} = \frac{18.63}{46.5} \), we can cross-multiply to find \( x \).

Cross-multiplying gives us:

\[ 39.1 \times 46.5 = 18.63 \times x \]

Now, let's calculate \( 39.1 \times 46.5 \):

\[ 39.1 \times 46.5 \approx 1821.15 \]

So the equation becomes:

\[ 1821.15 = 18.63 \times x \]

Next, we can solve for \( x \) by dividing both sides by \( 18.63 \):

\[ x = \frac{1821.15}{18.63} \]

Now, calculating that gives:

\[ x \approx 97.667 \]

So the solution is approximately:

\[ x \approx 97.67 \] (rounded to two decimal places).
