Add the following 16, 8.7, 0.94, 6.8 and 7.77

Answer

To solve the problem of adding the numbers 16, 8.7, 0.94, 6.8, and 7.77, we will follow these steps:

### Step 1: Write the numbers vertically
Align the numbers by their decimal points for easier addition.

```
16.00
+ 8.70
+ 0.94
+ 6.80
+ 7.77
```

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

- **Hundredths place**:
- 0 + 0 + 4 + 0 + 7 = 11 (write down 1 and carry over 1)

- **Tenths place**:
- 0 + 7 + 9 + 8 + 7 = 31, plus the 1 carried over = 32 (write down 2 and carry over 3)

- **Units place**:
- 6 + 8 + 0 + 6 + 7 = 27, plus the 3 carried over = 30 (write down 0 and carry over 3)

- **Tens place**:
- 1 + 0 + 0 + 0 + 0 = 1, plus the 3 carried over = 4 (write down 4)

### Step 3: Combine the results
Now, combine the results from each column to get the final sum:

```
40.21
```

### Final Answer:
The sum of 16, 8.7, 0.94, 6.8, and 7.77 is **40.21**.
