Let's solve each problem step by step by interpreting the place values shown in the tables. We'll express each number in standard form (whole number) based on the digits provided in their respective place value columns.

---

Problem 1

Place Values:
- Thousands: 6
- Tens: 49
- Ones: 7

But wait — Tens = 49? That’s not possible because a single digit in the "Tens" column can't be more than 9. However, in this case, it seems like the Tens column is showing 49 tens, which means:

> 49 tens = 49 × 10 = 490

So:
- Thousands: 6 → 6,000
- Tens: 49 → 490
- Ones: 7 → 7

Add them:
6,000 + 490 + 7 = 6,497

✔ Answer: 6,497

Problem 2

Place Values:
- Ten Thousands: 1
- Thousands: 80
- Hundreds: 6
- Tens: 33

Now interpret:
- Ten Thousands: 1 → 10,000
- Thousands: 80 → 80 × 1,000 = 80,000
- Hundreds: 6 → 600
- Tens: 33 → 33 × 10 = 330

Total:
10,000 + 80,000 = 90,000
90,000 + 600 = 90,600
90,600 + 330 = 90,930

✔ Answer: 90,930

---

Problem 3

Place Values:
- Thousands: 6
- Hundreds: 9
- Ones: 16

Interpret:
- Thousands: 6 → 6,000
- Hundreds: 9 → 900
- Ones: 16 → 16

Total: 6,000 + 900 + 16 = 6,916

✔ Answer: 6,916

---

Problem 4

Place Values:
- Ten Thousands: 3
- Thousands: 1
- Hundreds: 22
- Tens: 4
- Ones: 48

Break it down:
- Ten Thousands: 3 → 30,000
- Thousands: 1 → 1,000
- Hundreds: 22 → 22 × 100 = 2,200
- Tens: 4 → 40
- Ones: 48 → 48

Total:
30,000 + 1,000 = 31,000
31,000 + 2,200 = 33,200
33,200 + 40 = 33,240
33,240 + 48 = 33,288

✔ Answer: 33,288

---

Problem 5

Place Values:
- Hundreds: 4
- Tens: 4
- Ones: 21

Interpret:
- Hundreds: 4 → 400
- Tens: 4 → 40
- Ones: 21 → 21

Total: 400 + 40 + 21 = 461

✔ Answer: 461

Problem 6

Place Values:
- Hundreds: 2
- Hundreds: 3
- Tens: 18
- Ones: 2

Wait — two "Hundreds"? Let's look again.

The table has:
- Hundreds: 2
- Hundreds: 3
- Tens: 18
- Ones: 2

This appears to be a typo or mislabeling. But likely, it's meant to be:
- Hundreds: 2 and 3 → total hundreds = 2 + 3 = 5 → 500
- Tens: 18 → 18 × 10 = 180
- Ones: 2 → 2

But that would be: 500 + 180 + 2 = 682

Alternatively, maybe it's:
- Hundreds: 2 (first), then another 3 → but only one "Hundreds" column?

Wait — looking at the format, it might be:
- Hundreds: 2
- Hundreds: 3 → perhaps it's 2 hundreds and 3 hundreds? That would be 5 hundreds → 500

But better interpretation: Maybe the Hundreds column has two entries? No, it's probably a mistake.

Wait — the table shows:
| Hundreds | Tens | Ones |
|----------|------|------|
| 2 | 18 | 2 |
| 3 | | |

Ah! This is likely two rows:
- First row: 2 hundreds, 18 tens, 2 ones
- Second row: 3 hundreds

But no — the table has only one row per problem. Wait — actually, in Problem 6, there are two lines under "Hundreds", so likely:
- Hundreds: 2 and 3 → total 5 hundreds → 500
- Tens: 18 → 180
- Ones: 2 → 2

So: 500 + 180 + 2 = 682

But that doesn’t make sense with the layout.

Wait — let's re-express: The table is labeled as:
```
Hundreds | Tens | Ones
2 | 18 | 2
3 | |
```

That suggests:
- 2 hundreds, 18 tens, 2 ones → 200 + 180 + 2 = 382
- Plus another 3 hundreds → 300

So total: 382 + 300 = 682

But why split it? Probably just 2 hundreds and 3 hundreds → 5 hundreds.

But that’s not how it's structured.

Alternatively, perhaps the hundreds are stacked: 2 and 3 → 2+3=5 → 500
Tens: 18 → 180
Ones: 2 → 2
Total: 500 + 180 + 2 = 682

✔ Answer: 682

Problem 7

Place Values:
- Ten Thousands: 9
- Thousands: 2
- Hundreds: 3
- Tens: 4
- Ones: 19

Break down:
- Ten Thousands: 9 → 90,000
- Thousands: 2 → 2,000
- Hundreds: 3 → 300
- Tens: 4 → 40
- Ones: 19 → 19

Total:
90,000 + 2,000 = 92,000
92,000 + 300 = 92,300
92,300 + 40 = 92,340
92,340 + 19 = 92,359

✔ Answer: 92,359

Problem 8

Place Values:
- Ten Thousands: 8
- Thousands: 9
- Hundreds: 2
- Tens: 18
- Ones: 9

Break down:
- Ten Thousands: 8 → 80,000
- Thousands: 9 → 9,000
- Hundreds: 2 → 200
- Tens: 18 → 180
- Ones: 9 → 9

Total:
80,000 + 9,000 = 89,000
89,000 + 200 = 89,200
89,200 + 180 = 89,380
89,380 + 9 = 89,389

✔ Answer: 89,389

---

Problem 9

Place Values:
- Hundreds: 1
- Tens: 17
- Ones: 3

Break down:
- Hundreds: 1 → 100
- Tens: 17 → 170
- Ones: 3 → 3

Total: 100 + 170 + 3 = 273

✔ Answer: 273

---

Problem 10

Place Values:
- Thousands: 1
- Hundreds: 21
- Ones: 21

Break down:
- Thousands: 1 → 1,000
- Hundreds: 21 → 21 × 100 = 2,100
- Ones: 21 → 21

Total: 1,000 + 2,100 = 3,100 + 21 = 3,121

✔ Answer: 3,121

Problem 11

Place Values:
- Hundreds: 1
- Tens: 66
- Ones: 9

Break down:
- Hundreds: 1 → 100
- Tens: 66 → 660
- Ones: 9 → 9

Total: 100 + 660 + 9 = 769

✔ Answer: 769

---

Problem 12

Place Values:
- Tens: 37
- Ones: 8

Break down:
- Tens: 37 → 37 × 10 = 370
- Ones: 8 → 8

Total: 370 + 8 = 378

✔ Answer: 378
