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.
Use front-end estimation to estimate the sum.
8.86 + 9.43 + 5.75

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
8 + 9 + 5 + 2 = 24
