`sqrt(324)/1.5=?/sqrt(256)`

Options

A. 192
B. 432
C. 288
D. 122

Answer

To solve the equation \( \frac{\sqrt{324}}{1.5} = \frac{?}{\sqrt{256}} \), we will follow these steps:

### Step 1: Calculate \( \sqrt{324} \)
First, we need to find the square root of 324.

\[ \sqrt{324} = 18 \]

### Step 2: Divide by 1.5
Next, we will divide the result by 1.5.

\[ \frac{18}{1.5} = 12 \]

### Step 3: Calculate \( \sqrt{256} \)
Now, we need to find the square root of 256.

\[ \sqrt{256} = 16 \]

### Step 4: Set up the equation
Now we can set up the equation with the results we found:

\[ 12 = \frac{?}{16} \]

### Step 5: Solve for ?
To find the value of ?, we will multiply both sides of the equation by 16.

\[ ? = 12 \times 16 \]

Calculating this gives:

\[ ? = 192 \]

### Final Answer
Thus, the value of the question mark is:

\[ ? = 192 \]
