Given:

8,74,612 and 4,28,358

To find:

Estimate the difference.

Solution:

Estimate means to round off the numbers. To find the estimation of the given numbers first we need to round off and then do the subtraction.

In the question, it is mentioned to find the difference by rounding to the nearest 100.

Rounding to nearest 100.

8,74,612 => 8,74,600 (since the right-side number of the hundreds place is less than 1)

4,28,358 => 4,28,400 (since the right-side number of the hundreds place is 5)

Subtracting:

8,74,600

- 4,28,400

_________

4,46,200

_________

Hence, the estimated difference of 8,74,612 and 4,28,358 by rounding to the nearest 100 is 4,46,200
