Final answer:
To estimate the sum of 894 + 651, round each number to the nearest hundred to get 900 + 700, resulting in an estimated sum of 1600.
Step-by-step explanation:
To estimate the sum of 894 and 651 by rounding each number to the nearest hundred and then adding, we first round each number individually. The number 894 rounds up to 900 because the tens digit, 9, is 5 or greater. The number 651 rounds up to 700 for the same reason. After rounding, we add the estimates to get our estimated sum:
- 894 rounds to 900
- 651 rounds to 700
Summing these rounded values:
900 + 700 = 1600
This is our estimated sum for 894 + 651 when each number is rounded to the nearest hundred.
