4,9 : 0,6 = X : 2,4 =

To solve the proportion \( 4.9 : 0.6 = X : 2.4 \), we can set up the equation as follows:

\[ \frac{4.9}{0.6} = \frac{X}{2.4} \]

Next, we can cross-multiply:

\[ 4.9 \cdot 2.4 = 0.6 \cdot X \]

Calculating the left side:

\[ 4.9 \cdot 2.4 = 11.76 \]

Now we have:

\[ 11.76 = 0.6 \cdot X \]

To solve for \( X \), divide both sides by \( 0.6 \):

\[ X = \frac{11.76}{0.6} \]

Calculating this gives:

\[ X = 19.6 \]

So, the answer is:

\[ X = 19.6 \]
