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. (d) 4,89,348 – 48,3654,89,348 – 48,365 Rounding off to nearest tens 4,89,348 is rounded off to 4,89,350 48,365 is rounded off to 48,370 So, Estimated answer = 4,89,350 − 48,370 ∴ Estimated answer = 4,40,980 Rounding off to nearest hundreds 4,89,348 is rounded off to 4,89,300 48,365 is rounded off to 48,400 So, Estimated answer = 4,89,300 − 48,400 ∴ Estimated answer = 4,40,900
