Add the following 63.5, 9.7, 0.8, 26.66 and 12.17

Answer

To solve the problem of adding the numbers 63.5, 9.7, 0.8, 26.66, and 12.17, we will follow these steps:

### Step 1: Write the numbers in a vertical format
Align the numbers by their decimal points to make addition easier.

```
63.50
+ 9.70
+ 0.80
+ 26.66
+ 12.17
```

### Step 2: Add the numbers column by column
Start from the rightmost column (the hundredths place) and move to the left.

- **Hundredths place**: 0 + 0 + 0 + 6 + 7 = 13 (write down 3 and carry over 1)
- **Tenths place**: 5 + 7 + 8 + 6 + 1 (carry) = 27 (write down 7 and carry over 2)
- **Units place**: 3 + 9 + 0 + 6 + 2 (carry) = 20 (write down 0 and carry over 2)
- **Tens place**: 6 + 0 + 0 + 2 + 1 (carry) = 9

Now, write down the total from the leftmost column to the rightmost column.

### Step 3: Combine the results
Putting all the results together, we have:

```
112.83
```

### Final Answer
The sum of 63.5, 9.7, 0.8, 26.66, and 12.17 is **112.83**.
