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

Answer 1

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.
