Y : 51,6 = 11,3 : 34,4

To solve the proportion \( y : 51.6 = 11.3 : 34.4 \), we can use cross multiplication. This means we can set up the equation as follows: \[ y \cdot 34.4 = 51.6 \cdot 11.3 \] Now, let's calculate \( 51.6 \cdot 11.3 \): \[ 51.6 \cdot 11.3 = 583.08 \] Now, we substitute this back into the equation: \[ y \cdot 34.4 = 583.08 \] Next, solve for \( y \): \[ y = \frac{583.08}{34.4} \] Now, let's perform the division: \[ y \approx 16.95 \] Thus, the value of \( y \) is approximately \( 16.95 \).
