Question

Give a rough estimate (by rounding off to nearest hundreds) and also a closer estimate (by rounding off to nearest tens):

$1, 08, 734 - 47, 599$

Accepted Answer

Given numbers are $1, 08, 734$ and $47, 599$ .

Now, let us estimate the given number to their nearest hundreds.

Rounding off to the nearest hundreds:

If the tens place is greater than $5$ , then write $0$ in the ones & tens place and add $1$ to the hundreds place.

If the tens place is less than $5$ , then write $0$ in the ones & tens place and retain the hundreds place.

Rounding off to the nearest tens:

If the ones place is greater than $5$ , then write $0$ in the ones place and add $1$ to the tens place.

If the ones place is less than $5$ , then write $0$ in the ones place and retain the tens place.

Thus, we have,

$1, 08, 734$ rounded off to its nearest tens is $1, 08, 730$ and rounded off to its nearest hundreds is $1, 08, 700$ .

$47, 599$ rounded off to its nearest tens is $47, 600$ and rounded off to its nearest hundreds is $47, 600$ .

Thus, we have, $1, 08, 700 - 47, 600 = 61, 100$ and $1, 08, 730 - 47, 600 = 61130$

Hence, the estimated difference of the numbers rounded to the nearest hundred is $61, 100$ and that rounded to the nearest tens is $61, 130$

Give a rough estimate (by rounding off to nearest hundreds) and also a closer estimate (by rounding off to nearest tens):

$1, 08, 734 - 47, 599$
