Estimate 12345 * 6789 with step-by-step explanation plzz
Dear Student,
For finding the estimated product, we should round off the number in such a way that calculation becomes easier but error remains minimum.
Here, rounding off the numbers to thousandth place should give desired results
Rounding off 12345 ( to thousandth place) = 12000
( As digit in hundreth place (3) is less than 5, so thousandth digit remains unchanged and digits to its right becomes 0.)
Rounding off 6789 ( to thousandth place) = 7000
( As digit in hundreth place (7) is greater than 5, thousandth place is increased by 1. So thousandth place becomes 7. The digits to the right of thousandth place become 0. )
Estimated Product =
