The value of `4+ 44/10+404/100+444/1000+4/10000` is:

Options

A. 12.8944
B. 12.8844
C. 12.8804
D. 12.8224

Answer

To solve the expression \( 4 + \frac{44}{10} + \frac{404}{100} + \frac{444}{1000} + \frac{4}{10000} \), we will break it down step by step.

### Step 1: Convert each term to decimal form
1. The first term is \( 4 \).
2. The second term is \( \frac{44}{10} = 4.4 \).
3. The third term is \( \frac{404}{100} = 4.04 \).
4. The fourth term is \( \frac{444}{1000} = 0.444 \).
5. The fifth term is \( \frac{4}{10000} = 0.0004 \).

### Step 2: Add all the decimal values together
Now we will add all the decimal values we calculated:
\[ 4 + 4.4 + 4.04 + 0.444 + 0.0004 \]

### Step 3: Perform the addition
Let's add them step by step:
1. \( 4 + 4.4 = 8.4 \)
2. \( 8.4 + 4.04 = 12.44 \)
3. \( 12.44 + 0.444 = 12.884 \)
4. \( 12.884 + 0.0004 = 12.8844 \)

### Final Result
The value of the expression \( 4 + \frac{44}{10} + \frac{404}{100} + \frac{444}{1000} + \frac{4}{10000} \) is \( 12.8844 \).
