Question

Match the estimated sum by rounding to nearest thousands.

• A. $8000$
• B. $7000$
• C. $18000$

Answer 1

For rounding off a number by nearest thousand, we look at the hundreds place digit of the number.

If the hundreds place digit is less than 5, then the number will round down.

If the hundreds place digit is greater than or equal to 5, then the number will round up.

For 7092 + 1425, we round off the numbers to 7000 + 1000 = 8000



For 9825 + 8002, we round off and estimate 10000 + 8000 = 18000



And for 5924 + 1345 we round off to 6000 + 1000 and arrive at an estimation of 6000+ 1000 = 7000.
