To Nearest Hundreds

There are certain number of students in a class. This is approximated to nearest hundreds. Approximate value is 600 and the absolute error is 25. If exact value is less than the approximated value, then fond the relative error. (Correct to two decimal places).

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 (d) 4,89,348 – 48,365 Make four more such examples.
