Question

Estimate 12,457-3,987 by rounding to greatest place

Answer 1

Question

Estimate and subtract 12,457 - 3987 by rounding to greatest place.

Required answer

12,457 estimated to its greatest place, i.e. ten thousands = 10,000

3987 estimated to its greatest place, i.e. thousands = 4000

Difference of both the estimates, i.e. 10,000 and 4000 = 9600

Hence, 9600 is the answer.
