9 + 10 + 6 + 2 = 27
9 + 10 + 6 + 2 = 27
10 + 10 + 10 + 2 = 32
10 + 10 + 10 + 2 = 32
8 + 9 + 5 + 1 = 23
8 + 9 + 5 + 1 = 23
8 + 9 + 5 + 2 = 24

To use front-end estimation, we round each of the numbers to the nearest whole number and then add them up:
8.86 rounds to 9
9.43 rounds to 9
5.75 rounds to 6
Now we add them up:
9 + 9 + 6 = 24
So, the estimated sum is 24.
To use front-end estimation to estimate the sum 8.86 + 9.43 + 5.75, you can round each number to the nearest whole number by looking at the digits in the tenths place.
8.86 rounds to 9
9.43 rounds to 9
5.75 rounds to 6
Now, add these rounded numbers together:
9 + 9 + 6 = 24
Thus, the estimated sum is 24.
To estimate the sum using front-end estimation, you will round each number to its greatest place value.
Round 8.86 to 9, 9.43 to 9, and 5.75 to 6.
Then, add these rounded numbers: 9 + 9 + 6 = 24.
Therefore, the estimated sum is 24.
