63.05 , 24.839 , 3.7 , 16.85

Answer

To solve the problem of adding the numbers 63.05, 24.839, 3.7, and 16.85, we will follow these steps:

### Step-by-Step Solution:

1. **Align the Numbers by Decimal Points**:
Write the numbers in a column, aligning them by their decimal points. This helps in adding them correctly.
```
63.050
24.839
3.700
16.850
```

2. **Add Zeros for Clarity**:
To make addition easier, we can add zeros to the right of the decimal where necessary. This gives us:
```
63.050
24.839
03.700
16.850
```

3. **Add the Numbers Column by Column**:
Start adding from the rightmost column (thousandths) to the leftmost column (tens).

- **Thousandths place**: 0 + 9 + 0 + 0 = 9
- **Hundredths place**: 5 + 3 + 7 + 5 = 20 (write down 0 and carry over 2)
- **Tenths place**: 0 + 8 + 3 + 6 + 2 (carry) = 19 (write down 9 and carry over 1)
- **Units place**: 3 + 4 + 0 + 1 (carry) = 8
- **Tens place**: 6 + 2 + 0 + 1 (carry) = 9
- **Hundreds place**: 0 + 0 + 0 + 0 = 0

So, we write down the results:
```
109.439
```

4. **Final Result**:
The sum of the numbers 63.05, 24.839, 3.7, and 16.85 is **109.439**.

### Final Answer:
**109.439**
