Question

Estimate by rounding off the numbers using reasonable estimate:

965 + 2896 + 5965

Accepted Answer

To estimate by rounding off the numbers using reasonable estimate: $965 + 2896 + 5965$

For this, we need to round off each number to its greatest place.

i.e. round off $965$ to its nearest hundreds, round off $2896, 5965$ to their nearest thousands.

In $965$ , ten's place digit is greater than $5$ . So, ten's place and one's place is replaced by zero and hundred's place is increased by one.

The value obtained when $965$ is rounded off to the nearest hundreds is $1000$ .

In $2896$ , hundred's place digit is greater than $5$ . So, hundred's place, ten's place and one's place is replaced by zero and thousand's place is increased by one.

The value obtained when $2896$ is rounded off to the nearest thousands is $3000$ .

Similarly, the value obtained when $5965$ is rounded of the nearest thousands is $6000$ .

Now, $1000 + 3000 + 6000 = 10000$

Therefore, the estimated sum $= 10000$

Estimate by rounding off the numbers using reasonable estimate: $965 + 2896 + 5965$
