Fourteenth Problem: 252 - 247

Ones: 2 - 7 → borrow from tens.
- Tens digit 5 becomes 4, ones become 12.
- 12 - 7 = 5

Tens: 4 - 4 = 0

Hundreds: 2 - 2 = 0 → we don’t write leading zero

✔ Answer: 5

Wait — let’s double-check that.

252 - 247:

You can also think: 247 + 5 = 252 → yes, correct.

But in standard form, it’s just 5, but since it’s a 3-digit worksheet, maybe they expect 005? No — usually we just write 5.

Actually, looking at the format, all answers are written as 3 digits if needed. But 5 is fine as “5” or “005”? Let’s see the example: 347 is 3 digits.

In this case, 252 - 247 = 5 → so answer is 5

But to match format, perhaps write as 005? No — that’s not standard. In math, we don’t pad with zeros unless specified.

Looking back at the worksheet, the example answer is 347 — three digits. But for 5, it should be just 5.

However, in column subtraction, sometimes you leave blank spaces. But here, since it’s a grid, probably write 5 as is.

Actually, let me recalculate:

252
-247
_____
Start from right:

2 - 7 → borrow → 12 - 7 = 5
Middle: 4 (since 5 became 4) - 4 = 0
Left: 2 - 2 = 0 → so result is 005? But we don’t write leading zeros.

Standard practice: 5

But to be safe, let’s check: 252 - 247 = 5 → correct.

We’ll write 5

---

Fifteenth Problem: 612 - 104

Ones: 2 - 4 → borrow from tens.
- Tens digit 1 becomes 0, ones become 12.
- 12 - 4 = 8

Tens: 0 - 0 = 0

Hundreds: 6 - 1 = 5

✔ Answer: 508

Wait — tens place: after borrowing, tens digit was 1, became 0. Then subtract 0 → 0. So yes, 508.

Double-check: 612 - 104 = 508 → correct.

---

Now, let’s list all answers in order:

Row 1: 347 (example), 429, 359
Row 2: 259, 609, 449
Row 3: 313, 529, 359
Row 4: 249, 307, 269
Row 5: 472, 5, 508

Wait — the last one in row 5 is 612 - 104 = 508, yes.

And 252 - 247 = 5.

But let me confirm 252 - 247 again:

252
- 247
------
Start: 2 < 7 → borrow from 5 → 12 - 7 = 5
Then 4 (was 5, borrowed) - 4 = 0
Then 2 - 2 = 0 → so 005 → but we write 5.

Yes.

Final Answers in grid order:

Column 1:
347 (done)
259
313
249
472

Column 2:
429
609
529
307
5

Column 3:
359
449
359
269
508

So the completed worksheet answers are:

First row: 347, 429, 359
Second row: 259, 609, 449
Third row: 313, 529, 359
Fourth row: 249, 307, 269
Fifth row: 472, 5, 508

I think that’s all.

Final Answer:
The answers to the subtraction problems are:
347, 429, 359,
259, 609, 449,
313, 529, 359,
249, 307, 269,
472, 5, 508
