Select the correct answerThe fourth proportional to 2,12, and 3 isOptions11814225

1. ### Break Down the Problem

We need to find the fourth proportional to the numbers 2, 12, and 3. The fourth proportional $x$ to three numbers $a, b, c$ can be found using the proportion:

$\frac{a}{b} = \frac{c}{x}$

2. ### Relevant Concepts

The fourth proportional is defined as follows:

Given three quantities $a, b, c$, the fourth proportional $x$ can be calculated using the formula:

$x = \frac{b \cdot c}{a}$

Here, $a = 2$, $b = 12$, and $c = 3$.

3. ### Analysis and Detail

Let's substitute the values into the formula:

$x = \frac{12 \cdot 3}{2}$

Calculating this step-by-step:

1. Calculate the product of $b$ and $c$: $12 \cdot 3 = 36$

2. Now divide by $a$: $x = \frac{36}{2} = 18$

4. ### Verify and Summarize

The fourth proportional to 2, 12, and 3 is calculated to be 18.

Final Answer

The fourth proportional to 2, 12, and 3 is $\boxed{18}$.
