Options

A. 44.22
B. 77.22
C. 74.22
D. 47.22

Explanation

To solve the expression \(3.6 + 36.6 + 3.66 + 0.36 + 3.0\), we will follow these steps:

### Step 1: Write down the expression
We start with the expression:
\[ 3.6 + 36.6 + 3.66 + 0.36 + 3.0 \]

### Step 2: Group the numbers for easier addition
We can group the numbers in pairs for easier addition:
\[ (3.6 + 36.6) + (3.66 + 0.36) + 3.0 \]

### Step 3: Calculate the first group
Now, we calculate the first group:
\[ 3.6 + 36.6 = 40.2 \]

### Step 4: Calculate the second group
Next, we calculate the second group:
\[ 3.66 + 0.36 = 4.02 \]

### Step 5: Add the results from Step 3 and Step 4
Now we add the results from Step 3 and Step 4 along with the remaining number:
\[ 40.2 + 4.02 + 3.0 \]

### Step 6: Calculate \(40.2 + 4.02\)
First, we add \(40.2\) and \(4.02\):
\[ 40.2 + 4.02 = 44.22 \]

### Step 7: Add \(44.22 + 3.0\)
Finally, we add \(44.22\) and \(3.0\):
\[ 44.22 + 3.0 = 47.22 \]

### Final Answer
Thus, the final result is:
\[ \boxed{47.22} \]
