Estimate each of the following products by rounding off each number to the nearest hundred :
`423xx158`

Answer

To estimate the product of 423 and 158 by rounding each number to the nearest hundred, follow these steps:

### Step 1: Round 423 to the nearest hundred
- Look at the tens digit of 423, which is 2.
- Since 2 is less than 5, we do not increase the hundreds place.
- Therefore, 423 rounded to the nearest hundred is **400**.

### Step 2: Round 158 to the nearest hundred
- Look at the tens digit of 158, which is 5.
- Since 5 is equal to or greater than 5, we increase the hundreds place by 1.
- Therefore, 158 rounded to the nearest hundred is **200**.

### Step 3: Calculate the product of the rounded numbers
- Now, multiply the rounded numbers: 400 and 200.
- \( 400 \times 200 = 80,000 \).

### Final Answer
The estimated product of 423 and 158, after rounding to the nearest hundred, is **80,000**.
