Toppr Admin · Accepted Answer

Rounding off -28-292- to its greatest place i-e- thousands place - 28-000- Rounding off -21-496- to its greatest place i-e- thousands place - 21-000-Hence- estimated difference difference - 28-000 - 21-000 - 7-000-

Estimate the following by rounding off each number nearest to its greatest place:
$$28,292 - 21,496$$

Rounding off $$28,292$$ to its greatest place i.e.
thousands place $$= 28,000$$
Rounding off $$21,496$$ to its greatest place i.e.
thousands place $$= 21,000$$
Hence, estimated difference difference $$= 28,000 - 21,000 = 7,000$$
