Rounding off 3480 to nearest 100 gives 3500 as tens digit 8 is greater than 5.
Rounding off 520 to nearest 100 gives 500 as tens digit 2 is less than 5.
So, estimated quotient = 3500÷500 = 7
Estimate the quotient of 1156 divided by 220 by rounding off to nearest 100.
Question 2(d) Give a rough estimate (by rounding off to nearest hundreds) and also a closer estimate (by rounding off to nearest tens): 4,89,348 – 48,365
