D. none of these

Answer

To solve the problem \(2 - 0.7\), we can follow these steps:

### Step 1: Rewrite the numbers
We can rewrite the whole number 2 as a decimal to make the subtraction easier.
So, we write:
\[ 2 = 2.0 \]

### Step 2: Set up the subtraction
Now we can set up the subtraction:
\[ 2.0 - 0.7 \]

### Step 3: Align the decimal points
Align the decimal points for clarity:
```
2.0
- 0.7
```

### Step 4: Subtract the numbers
Now, we subtract:
- Start from the right: \(0 - 7\) cannot be done, so we borrow 1 from the 2 (which becomes 1), making the 0 into 10.
- Now we have \(10 - 7 = 3\).
- Next, we subtract the whole numbers: \(1 - 0 = 1\).

Putting it all together, we get:
\[ 2.0 - 0.7 = 1.3 \]

### Step 5: Write the final answer
Thus, the answer to \(2 - 0.7\) is:
\[ \boxed{1.3} \]
