Answer

To find the approximation of 8198936 to the nearest thousand, we can follow these steps:

### Step 1: Identify the number to round
The number we are working with is **8198936**.

### Step 2: Locate the thousands place
In the number 8198936, the thousands place is represented by the digit **8**, which is the fourth digit from the right. The number can be broken down as follows:
- Millions: 8
- Hundred Thousands: 1
- Ten Thousands: 9
- Thousands: **8**
- Hundreds: 9
- Tens: 3
- Units: 6

### Step 3: Look at the hundreds place
To round to the nearest thousand, we need to look at the digit in the hundreds place, which is **9** (the third digit from the right).

### Step 4: Apply rounding rules
According to rounding rules:
- If the hundreds digit is **5 or greater**, we round up.
- If the hundreds digit is **less than 5**, we round down.

In this case, since the hundreds digit is **9** (which is greater than 5), we will round up.

### Step 5: Round the number
When rounding up, we increase the thousands digit (which is 8) by 1, making it **9**, and change all digits to the right of the thousands place to **0**.

Thus, the rounded number becomes:
- Thousands: **9**
- Hundreds: **0**
- Tens: **0**
- Units: **0**

So, the approximation of 8198936 to the nearest thousand is **8199000**.

### Final Answer
The approximation of 8198936 to the nearest thousand is **8199000**.
