Mark against the correct answer
`1.1-0.3=?`

Options

A. 0.8
B. 0.08
C. 8
D. none of these

Answer

To solve the question \(1.1 - 0.3\), we will follow these steps:

### Step 1: Align the numbers
Align the numbers vertically by placing the decimal points in line:

```
1.1
- 0.3
```

### Step 2: Subtract the numbers
Now, we will subtract the numbers starting from the rightmost digit:

- In the tenths place: \(1 - 3\) cannot be done directly, so we need to borrow 1 from the whole number (1 becomes 0, and we add 10 to the tenths place).

So, \(11 - 3 = 8\).

- In the whole number place: After borrowing, we have \(0 - 0 = 0\).

Putting it all together, we have:

```
1.1
- 0.3
------
0.8
```

### Final Answer
Thus, \(1.1 - 0.3 = 0.8\).

### Marking the Correct Option
Looking at the options:
- Option a: 0.8 (Correct)
- Option b: 0.08
- Option c: 8
- Option d: None of these

The correct answer is **Option a: 0.8**.
