`5xx ? = 8484 div 4`

Options

A. 444.2
B. 424.2
C. 442.2
D. 422.2

Explanation

To solve the equation \( 5 \times ? = \frac{8484}{4} \), we can follow these steps:

### Step 1: Calculate \( \frac{8484}{4} \)
First, we need to divide 8484 by 4.

\[ 8484 \div 4 = 2121 \]

### Step 2: Set up the equation
Now we can rewrite the equation with the value we just calculated:

\[ 5 \times ? = 2121 \]

### Step 3: Isolate the question mark
To find the value of the question mark (let's denote it as \( x \)), we need to isolate \( x \) by dividing both sides of the equation by 5:

\[ ? = \frac{2121}{5} \]

### Step 4: Calculate \( \frac{2121}{5} \)
Now we perform the division:

\[ 2121 \div 5 = 424.2 \]

### Step 5: Conclusion
Thus, the value of the question mark is:

\[ ? = 424.2 \]

### Summary of Steps
1. Calculate \( \frac{8484}{4} \) to get 2121.
2. Rewrite the equation as \( 5 \times ? = 2121 \).
3. Isolate \( ? \) by dividing both sides by 5.
4. Calculate \( \frac{2121}{5} \) to find \( ? \).
