Best Answer

To mentally estimate the product of 313 and 489, you can round both numbers to the nearest hundred to simplify the calculation. 313 rounds to 300 and 489 rounds to 500. Multiply these rounded numbers together to get 300 x 500 = 150,000. This is a rough estimate of the product of 313 and 489.

You would round 313 to 300 and 489 to 500 and multiply 300 by 500. You should get 150,000. The real answer should be near 150,000.
