336.66 + 663.33 + 636.63 =?

Options

A. 1663. 26
B. 1646 .24
C. 1636.62
D. 1633.16

Answer

To find the value that will come in place of the question mark (?) in the equation:

\[ 336.66 + 663.33 + 636.63 = ? \]

we will perform the addition step by step.

### Step 1: Align the Numbers
First, we align the numbers by their decimal points:

```
336.66
+ 663.33
+ 636.63
```

### Step 2: Add the Numbers Column by Column
We will add the numbers starting from the rightmost column (the hundredths place) and move to the left.

1. **Hundredths Place**:
- \(6 + 3 + 3 = 12\)
- Write down 2 and carry over 1.

2. **Tenths Place**:
- \(6 + 3 + 6 + 1 (carry) = 16\)
- Write down 6 and carry over 1.

3. **Units Place**:
- \(6 + 6 + 6 + 1 (carry) = 19\)
- Write down 9 and carry over 1.

4. **Tens Place**:
- \(3 + 6 + 3 + 1 (carry) = 13\)
- Write down 3 and carry over 1.

5. **Hundreds Place**:
- \(3 + 6 + 6 + 1 (carry) = 16\)
- Write down 6 and carry over 1.

6. **Thousands Place**:
- Since there is no other number, we just write down the carry, which is 1.

### Step 3: Combine the Results
Now, we combine all the results we wrote down:

```
1 (carry)
636.63
+ 663.33
+ 336.66
-----------
1636.62
```

### Final Answer
Thus, the value that will come in place of the question mark (?) is:

\[ 1636.62 \]
