Question

Estimate the product of 567 and 423 by rounding off each number to the nearest hundred.

Answer 1

We start by rounding off each number to the nearest hundred
In 567 , the tens digit is 6 so it is greater than 5. Hence, on rounding up to the nearest hundred we get 600.

Similarly, considering 423, the tens digit 2 is less than 5. So, 423 will be rounded down to 400.
so, estimated product to nearest hundered will be
= 600 × 400 = 2,40,000.
