Q.1. Estimate the following using the general rule
730+998
1700

Solution: To estimate the following using a general rule, round off each number to its greatest place. Here the greatest place is hundreds, so round off given numbers to their nearest hundreds.
To round off, if the digit at tens place is less than 5, replace each one of the digits at tens and units place by 0 and keep all other digits as they are.
If the digit at tens place is greater than or equal to 5, increase the digit at hundreds place by 1 and replace each one of the digits at tens and ones place by 0.
Hence, the nearest hundred to 730 is 700 and nearest hundred to 998 is 1000
Therefore, estimated sum=1000+700=1700

Q.2. Estimate the following using the general rule.
796-314
500

Solution: To find: Estimated value of 796-314

We know that, If the digit at tens place is less than 5, replace each one of the digits at tens and units place by 0 and keep all other digits as they are. If the digit at tens place is greater than or equal to 5, increase the digit at hundreds place by 1 and replace each one of the digits at tens and ones place by 0.
Hence, 796 rounds off to 800 and 314 rounds off to 300
Therefore, Estimated difference =800-300=500

Q.3. Estimate the following using the general rule:
12,904+2,888
16,000

Solution: If the digit at hundreds place is less than 5, replace each one of the digits at hundreds, tens and units place by 0 and keep all other digits as they are.
If the digit at hundreds place is greater than or equal to 5, increase the digit at thousands place by 1 and replace each one of the digits at hundreds, tens and ones place by 0.
Hence, 12904 rounds off to 13000 and 2,888 rounds off to 3000
Therefore, Estimated sum=13000+3000=16000

Q.4. Estimate the following difference using the general rule.
28,292-21,496
7000

Solution: 28,292 rounds off to 28000.
21496 rounds off to 21000.
Estimated difference =28000-21000=7000.
