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).
