Estimate the answer by rounding 863 x 534 to the nearest 100

Answers

Answer:

Step-by-step explanation:

If I rounded to the nearest hundred it would look like this 900 and 500.

because the closest hundred type number is 900 and the same for the number 500

Answer:

450,000

Step-by-step explanation:

To estimate the answer by rounding 863 x 534 to the nearest 100, follow these steps:

1. Multiply the tens digit of both numbers: 8 x 5 = 40

2. Round each number to the nearest 100: 863 ≈ 900 and 534 ≈ 500

3. Multiply the rounded numbers: 900 x 500 = 450,000

4. The estimated answer to the nearest 100 is 450,000.

Therefore, when rounding 863 x 534 to the nearest 100, the estimated answer is 450,000.
