If `1.123 xx 3.211 = 3.122+` '_____' then the number in blank space is

Options

A. `0.483`
B. `0.0483`
C. `4.083`
D. `4.0083`

Answer

To solve the equation \( 1.123 \times 3.211 = 3.122 + x \), we will follow these steps:

### Step 1: Set up the equation
We start with the equation:
\[ 1.123 \times 3.211 = 3.122 + x \]
Here, we need to find the value of \( x \).

### Step 2: Calculate \( 1.123 \times 3.211 \)
Now, we will multiply \( 1.123 \) by \( 3.211 \):
\[ 1.123 \times 3.211 = 3.605453 \]
(You can use a calculator for this multiplication.)

### Step 3: Substitute the result back into the equation
Now we substitute the result back into the equation:
\[ 3.605453 = 3.122 + x \]

### Step 4: Isolate \( x \)
To find \( x \), we will subtract \( 3.122 \) from both sides of the equation:
\[ x = 3.605453 - 3.122 \]

### Step 5: Calculate \( x \)
Now, we perform the subtraction:
\[ x = 3.605453 - 3.122 = 0.483453 \]
(You can round this to \( 0.483 \) for simplicity.)

### Final Answer
Thus, the number in the blank space is:
\[ \boxed{0.483} \]
