Subtraction practice with place value charts for three-digit numbers.

Let's solve each subtraction problem step by step using the standard algorithm (borrowing when needed). We'll go through each of the six problems one at a time.

Problem 1:

```
9 2 5
- 3 8 9
-------
```

Step-by-step:

- Ones place: 5 - 9 → Can't do, so borrow from tens.
- Tens digit (2) becomes 1, and ones become 15.
- 15 - 9 = 6
- Tens place: 1 (after borrowing) - 8 → Can't do, so borrow from hundreds.
- Hundreds digit (9) becomes 8, and tens become 11.
- 11 - 8 = 3
- Hundreds place: 8 - 3 = 5

✔ Answer: 536

Problem 2:

```
8 4 2
- 4 7 8
-------
```

Step-by-step:

- Ones place: 2 - 8 → Can't do, borrow from tens.
- Tens digit (4) becomes 3, ones become 12.
- 12 - 8 = 4
- Tens place: 3 - 7 → Can't do, borrow from hundreds.
- Hundreds digit (8) becomes 7, tens become 13.
- 13 - 7 = 6
- Hundreds place: 7 - 4 = 3

✔ Answer: 364

Problem 3:

```
5 2 3
- 2 9 7
-------
```

Step-by-step:

- Ones place: 3 - 7 → Can't do, borrow from tens.
- Tens digit (2) becomes 1, ones become 13.
- 13 - 7 = 6
- Tens place: 1 - 9 → Can't do, borrow from hundreds.
- Hundreds digit (5) becomes 4, tens become 11.
- 11 - 9 = 2
- Hundreds place: 4 - 2 = 2

✔ Answer: 226

Problem 4:

```
6 3 4
- 3 7 9
-------
```

Step-by-step:

- Ones place: 4 - 9 → Can't do, borrow from tens.
- Tens digit (3) becomes 2, ones become 14.
- 14 - 9 = 5
- Tens place: 2 - 7 → Can't do, borrow from hundreds.
- Hundreds digit (6) becomes 5, tens become 12.
- 12 - 7 = 5
- Hundreds place: 5 - 3 = 2

✔ Answer: 255

Problem 5:

```
8 3 2
- 5 5 6
-------
```

Step-by-step:

- Ones place: 2 - 6 → Can't do, borrow from tens.
- Tens digit (3) becomes 2, ones become 12.
- 12 - 6 = 6
- Tens place: 2 - 5 → Can't do, borrow from hundreds.
- Hundreds digit (8) becomes 7, tens become 12.
- 12 - 5 = 7
- Hundreds place: 7 - 5 = 2

✔ Answer: 276

Problem 6:

```
7 2 6
- 4 4 7
-------
```

Step-by-step:

- Ones place: 6 - 7 → Can't do, borrow from tens.
- Tens digit (2) becomes 1, ones become 16.
- 16 - 7 = 9
- Tens place: 1 - 4 → Can't do, borrow from hundreds.
- Hundreds digit (7) becomes 6, tens become 11.
- 11 - 4 = 7
- Hundreds place: 6 - 4 = 2

✔ Answer: 279

✔ Final Answers:

1. 925 - 389 = 536
2. 842 - 478 = 364
3. 523 - 297 = 226
4. 634 - 379 = 255
5. 832 - 556 = 276
6. 726 - 447 = 279

You can now fill these answers into the blank rows in the worksheet. Let me know if you'd like a visual representation!
