Subtract:
0.612 from 3.4

Answer

To solve the problem of subtracting 0.612 from 3.4, we can follow these steps:

### Step-by-Step Solution:

1. **Write the numbers in a vertical format**:
We will write 3.4 on top and 0.612 below it, aligning the decimal points.

```
3.4
- 0.612
```

2. **Add zeros for easier subtraction**:
Since 0.612 has three decimal places, we can add two zeros to 3.4 to make it 3.400. This helps us align the numbers properly.

```
3.400
- 0.612
```

3. **Start subtracting from the rightmost digit**:
We will subtract each column starting from the right.

- **Rightmost column**: 0 - 2. We cannot subtract 2 from 0, so we need to borrow from the next column.
- **Next column**: 0 - 1. Again, we cannot subtract 1 from 0, so we need to borrow from the next column.
- **Next column**: 3 becomes 2 (after borrowing), and we turn the 0 into 10 (after borrowing from the previous column).

4. **Perform the subtraction**:
- Now we have 10 - 2 = 8 (from the rightmost column).
- Next, we have 9 - 1 = 8 (from the second column).
- Now, we need to subtract 2 from 13 (after borrowing from the previous column), so 13 - 6 = 7.

5. **Combine the results**:
Now we can write down the results of our subtraction:
- From the rightmost column: 8
- From the second column: 8
- From the third column: 7
- Don't forget to place the decimal point in the same position.

Thus, the answer is:
```
2.788
```

### Final Answer:
The result of subtracting 0.612 from 3.4 is **2.788**.
