Estimating the Sum of 7172 and 1654 to the Nearest Thousand

To estimate the sum of 7172 and 1654 to the nearest thousand, we need to follow these steps:

Step 1: Round the digits in the ones place to the nearest ten. In this case, 2 rounds to 0 and 4 rounds to 0.

Step 2: Add the rounded numbers. 7100 + 1600 = 8700

Step 3: Round the result to the nearest thousand. Since the hundreds digit is 7, which is greater than or equal to 5, we round up. The answer is 9000.

Therefore, the estimated sum of 7172 and 1654 to the nearest thousand is 9000.

Explanation:

Rounding the digits in the ones place to the nearest ten makes it easier to add the numbers mentally. The sum of 7172 and 1654 is 8826, but by rounding the digits in the ones place, we get 7100 + 1600 = 8700.

To round the result to the nearest thousand, we look at the hundreds digit, which is 7. Since it is greater than or equal to 5, we round up to the nearest thousand. Therefore, the estimated sum is 9000.

Estimating sums is a useful skill to have in our daily lives, especially when making quick calculations in our heads. By rounding numbers and using mental math, we can get approximate answers that are close enough to the actual answer.

9000 is round off to 8826
