Transcript

Question 2 Give a rough estimate (by rounding off to nearest hundreds) & also a closer estimate (by rounding off to nearest tens) : Make four more such examples. (b) 1,08,734 – 47,5991,08,734 – 47,599 Rounding off to nearest tens 1,08,734 is rounded off to 1,08,730 47,599 is rounded off to 47,600 So, Estimated answer = 1,08,730 − 47,600 ∴ Estimated answer = 61,130 Rounding off to nearest hundreds 1,08,734 is rounded off to 1,08,700 47,599 is rounded off to 47,600 So, Estimated answer = 1,08,730 − 47,600 ∴ Estimated answer = 61,100
