β’ Question:2
Give a rough estimate (by rounding off to nearest hundreds) and
also a closer estimate (by rounding off to nearest tens):
(a) 439 + 334 + 4, 317 (b) 1,08, 734 - 47,599 (c) 8325 - 491
β’ (d) 4, 89, 348 - 48, 365, Make four more such examples.
β’ (a) 439 + 334 + 4317
Rounding off to nearest hundreds, 439, 334, and 4317 may be
rounded off to 400, 300, and 4300 respectively.
β’ 400+300+4300=7000
Rounding off to nearest tens, 439, 334, and 4317 may be rounded
off to 440, 330, and 4320 respectively.
440+330+4320=5090
β’ (b) 1,08,734 - 47,599
