Estimate a range for each sum

example 7.42+13.97+101.2

7 to 101

To estimate a range for the sum of 7.42, 13.97, and 101.2, we can round each number to the nearest whole number and then add them together.

7.42 rounds to 7
13.97 rounds to 14
101.2 rounds to 101

Now, we add these rounded numbers together:
7 + 14 + 101 = 122

So, the estimated range for the sum of 7.42, 13.97, and 101.2 is 122.
