4,5:0,6= x:2,4

To solve the proportion \( \frac{4.5}{0.6} = \frac{x}{2.4} \), we can use cross-multiplication.

1. Cross-multiply: \[ 4.5 \cdot 2.4 = 0.6 \cdot x \]

2. Calculate \( 4.5 \cdot 2.4 \): \[ 4.5 \cdot 2.4 = 10.8 \]

3. Now we have the equation: \[ 10.8 = 0.6 \cdot x \]

4. To find \( x \), divide both sides by \( 0.6 \): \[ x = \frac{10.8}{0.6} \]

5. Calculate \( \frac{10.8}{0.6} \): \[ x = 18 \]

So, the value of \( x \) is \( 18 \).
