D. 2.1728

Answer

To solve the expression \( 0.4444 + 0.4444 + 0.444 + 0.44 + 0.4 \), we can follow these steps:

### Step 1: Group Similar Terms
First, we can group the terms that are the same or similar for easier addition. We have:
- Two \( 0.4444 \)
- One \( 0.444 \)
- One \( 0.44 \)
- One \( 0.4 \)

### Step 2: Add the Similar Terms
Now, let's add the two \( 0.4444 \):
\[ 0.4444 + 0.4444 = 0.8888 \]

### Step 3: Add the Remaining Terms
Next, we add the result \( 0.8888 \) to the other terms \( 0.444 \), \( 0.44 \), and \( 0.4 \):
\[ 0.8888 + 0.444 = 1.3328 \]
Now, add \( 0.44 \):
\[ 1.3328 + 0.44 = 1.7728 \]
Finally, add \( 0.4 \):
\[ 1.7728 + 0.4 = 2.1728 \]

### Final Answer
Thus, the final result of the expression \( 0.4444 + 0.4444 + 0.444 + 0.44 + 0.4 \) is:
\[ \boxed{2.1728} \]
