Step 3: Value of each digit

We analyze the place value of each digit in 8,351,207:

| Digit | Place Value | Value |
|-------|---------------------|-------|
| 8 | Millions | 8,000,000 |
| 3 | Hundred Thousands | 300,000 |
| 5 | Ten Thousands | 50,000 |
| 1 | Thousands | 1,000 |
| 2 | Hundreds | 200 |
| 0 | Tens | 0 |
| 7 | Ones | 7 |

Now answer the questions:

- The value of the digit 5 is: 50,000
- The value of the digit 7 is: 7
- The value of the digit 3 is: 300,000
- The value of the digit 2 is: 200
- The value of the digit 8 is: 8,000,000

Step 4: Fill in the number line

We are given:
- A point at 8,351,207
- A point at 8,351,210
- We need to fill in the boxes on the number line.

Since 8,351,210 is 3 more than 8,351,207, we can assume the number line increases by 1 each step.

So the numbers should be:
- Before 8,351,207: 8,351,206, 8,351,205, 8,351,204
- After 8,351,207: 8,351,208, 8,351,209, 8,351,210

But the boxes are arranged like this:

```
[____] [____] [____] ←→ 8,351,207 ←→ [____] [____] [____]
```

Assuming the arrow points from left to right and the spacing is consistent, the sequence around 8,351,207 would be:

- Left side (before): 8,351,204, 8,351,205, 8,351,206
- Right side (after): 8,351,208, 8,351,209, 8,351,210

So fill in:
- Left boxes: 8,351,204, 8,351,205, 8,351,206
- Right boxes: 8,351,208, 8,351,209, 8,351,210

Step 5: Expanded form

Write 8,351,207 in expanded form:

Break down each digit:

- 8,000,000 (8 millions)
- 300,000 (3 hundred thousands)
- 50,000 (5 ten thousands)
- 1,000 (1 thousand)
- 200 (2 hundreds)
- 0 tens → 0
- 7 ones → 7

So expanded form:

8,000,000 + 300,000 + 50,000 + 1,000 + 200 + 0 + 7

Or simplified:

8,000,000 + 300,000 + 50,000 + 1,000 + 200 + 7

Step 6: Fill in the blanks

#### a) 1,000,000 less than 8,351,207
- 8,351,207 - 1,000,000 = 7,351,207

#### b) 1,000 more than 8,351,207
- 8,351,207 + 1,000 = 8,352,207

#### c) 100,000 less than 8,351,207
- 8,351,207 - 100,000 = 8,251,207

#### d) 10 more than 8,351,207
- 8,351,207 + 10 = 8,351,217

#### e) 1 less than 8,351,207
- 8,351,207 - 1 = 8,351,206

2. 8,251,307 vs 8,351,207
- 8,251,307 < 8,351,207 → <

3. 8,351,207 vs 8,315,207
- Compare digits:
- 8,351,207 vs 8,315,207
- Both start with 8,3... but next digit: 5 vs 1 → 5 > 1 → so >

4. 8,351,207 vs 8,351,702
- Compare digit by digit:
- First 5 digits: 8,351,2 vs 8,351,7 → 2 < 7 → so <
