Toppr Admin · Accepted Answer

Rounding off -730- to its greatest place i-e- hundred place - 700-Rounding off -998- to its greatest place i-e-hundreds place - 1000-Hence- estimated sum - 700 - 1000 - 1700-

Estimate the following by rounding off each number nearest to its greatest place:
$$730 + 998$$

Rounding off $$730$$ to its greatest place i.e. hundred place $$= 700$$
Rounding off $$998$$ to its greatest place i.e.
hundreds place $$= 1000$$
Hence, estimated sum $$= 700 + 1000 = 1700$$

Estimate the following by rounding off each number nearest to its greatest place:$$730 + 998$$

Rounding off $$730$$ to its greatest place i.e. hundred place $$= 700$$Rounding off $$998$$ to its greatest place i.e.hundreds place $$= 1000$$Hence, estimated sum $$= 700 + 1000 = 1700$$

Estimate the following by rounding off each number nearest to its greatest place:
