Options

A. `21.6064`
B. `21.6932`
C. `21.6922`
D. `21.6964`

Answer

To evaluate the expression \( 326.7564 - 305.06 \), we will follow these steps:

### Step 1: Align the numbers
First, we need to align the numbers vertically by their decimal points. We can rewrite \( 305.06 \) as \( 305.0600 \) to match the number of decimal places in \( 326.7564 \).

```
326.7564
- 305.0600
```

### Step 2: Subtract starting from the right
Now, we will subtract each column starting from the rightmost digit.

1. **Thousandths place**: \( 4 - 0 = 4 \)
2. **Hundredths place**: \( 6 - 0 = 6 \)
3. **Tenths place**: \( 5 - 6 \) (we need to borrow since 5 is less than 6)
- Borrow 1 from the next column (the units place), making it \( 15 - 6 = 9 \) (the units place becomes \( 2 \)).
4. **Units place**: \( 2 - 0 = 2 \)
5. **Tens place**: \( 6 - 5 = 1 \)
6. **Hundreds place**: \( 3 - 3 = 0 \)

Putting it all together, we have:

```
326.7564
- 305.0600
-----------
21.6964
```

### Final Answer
Thus, the result of \( 326.7564 - 305.06 \) is \( 21.6964 \).
