Add the following 26.9, 19.74, 231.769 and 0.048

Answer

To solve the problem of adding the numbers 26.9, 19.74, 231.769, and 0.048, we will follow these steps:

### Step 1: Write the numbers in vertical order
We will arrange the numbers vertically, ensuring that the decimal points are aligned. This helps us to add the numbers correctly.

```
26.900
19.740
231.769
+ 0.048
```

### Step 2: Fill in the missing decimal places with zeros
To make the addition easier, we can add zeros to the end of the numbers that have fewer decimal places. This way, all numbers will have three decimal places.

```
26.900
19.740
231.769
+ 0.048
```

### Step 3: Add the numbers column by column
Now we will add the numbers starting from the rightmost column (thousandths place) and move to the left.

1. **Thousandths place**: 0 + 0 + 9 + 8 = 17 (write 7 and carry over 1)
2. **Hundredths place**: 0 + 4 + 6 + 4 + 1 (carry) = 15 (write 5 and carry over 1)
3. **Tenths place**: 9 + 7 + 7 + 0 + 1 (carry) = 24 (write 4 and carry over 2)
4. **Units place**: 6 + 9 + 1 + 0 + 2 (carry) = 18 (write 8 and carry over 1)
5. **Tens place**: 2 + 1 + 3 + 0 + 1 (carry) = 7 (write 7)
6. **Hundreds place**: 2 (from 231) = 2 (write 2)

Putting it all together, we get:

```
26.900
19.740
231.769
+ 0.048
---------
278.457
```

### Final Answer
The sum of 26.9, 19.74, 231.769, and 0.048 is **278.457**.
