obtain an estimate for the following computation by rounding the numbers so that the resulting arithmetic can easily be performed by hand or in your head. then, use a calculator to perform the computation. how reasonable is your estimate when compared to the actual answer?7.66+4.46+14.29round each number to the nearest integer. an estimate of the sum is ____

In this case, we'll have to carry out several steps to find the solution.

Step 01:

Data

7.66+4.46+14.29

number 1: 7.66

number 2: 4.46

number 3: 14.29

Step 02:

Round each number to the nearest integer.

number 1: 7.66 ===> 8

number 2: 4.46 ===> 4

number 3: 14.29 ===> 14

8 + 4 + 14 = 26

7.66+4.46+14.29 = 26.41

The estimate by rounding the numbers is reasonable but not totally accurate.

That is the full solution.
