15,04 : 26,88=m : 268,8

To solve the proportion \( \frac{15.04}{26.88} = \frac{m}{268.8} \), we can use cross-multiplication.

Cross-multiplying gives us:

\[ 15.04 \times 268.8 = 26.88 \times m \]

Now we'll calculate \( 15.04 \times 268.8 \):

\[ 15.04 \times 268.8 = 4046.592 \]

So, we have:

\[ 4046.592 = 26.88 \times m \]

Now, we can solve for \( m \):

\[ m = \frac{4046.592}{26.88} \]

Calculating this gives:

\[ m \approx 150.0 \]

Thus, the value of \( m \) is approximately \( 150.0 \).
