Horizontally Arranged Three-Digit Minus One-Digit Subtraction(100 ... - Free Printable

The task involves solving a series of 3-digit minus 1-digit subtraction problems. Below, I will explain the general approach to solving these problems and provide an example solution.

General Approach:

1. Align the numbers: Ensure the digits are aligned correctly (ones place under ones place, tens place under tens place, etc.).
2. Subtract the ones place: Subtract the 1-digit number from the ones place of the 3-digit number.
- If the digit in the ones place of the 3-digit number is smaller than the 1-digit number, you will need to borrow from the tens place.
3. Write the result: Write down the result of the subtraction.

Example Solution:

Let's solve one of the problems as an example: 247 - 9.

#### Step-by-Step:
1. Align the numbers:
```
247
- 9
```

2. Subtract the ones place:
- The ones place of 247 is 7.
- Subtract 9 from 7: \( 7 - 9 \).
- Since 7 is less than 9, we need to borrow 1 from the tens place.
- Borrowing 1 from the tens place (4 becomes 3), the ones place becomes \( 17 \) (because 10 + 7 = 17).
- Now, subtract: \( 17 - 9 = 8 \).

3. Subtract the tens place:
- After borrowing, the tens place is now 3.
- Subtract 0 from 3 (since there is no digit in the tens place of 9): \( 3 - 0 = 3 \).

4. Subtract the hundreds place:
- The hundreds place remains unchanged: \( 2 - 0 = 2 \).

5. Combine the results:
- The final answer is \( 238 \).

So, 247 - 9 = 238.

Applying the Same Method to Other Problems:

You can apply this method to all the problems in the worksheet. Here are a few more examples:

- 559 - 5:
- Subtract 5 from 9: \( 9 - 5 = 4 \).
- The tens and hundreds places remain unchanged.
- Final answer: 554.

- 695 - 7:
- Subtract 7 from 5: Borrow 1 from the tens place (9 becomes 8), making the ones place \( 15 \).
- \( 15 - 7 = 8 \).
- Subtract 0 from 8: \( 8 - 0 = 8 \).
- Subtract 0 from 6: \( 6 - 0 = 6 \).
- Final answer: 688.
