Finding the Error in the Given Approximations

To find the error in the given approximations, we need to compare the approximations with the actual values. Let's calculate the errors for each case:

1) For the approximation of 0.1975 as 0.198: - Actual value: 0.1975 - Approximation: 0.198 - Error = Actual value - Approximation = 0.1975 - 0.198 = -0.0005

2) For the approximation of -3.254 as -3.25: - Actual value: -3.254 - Approximation: -3.25 - Error = Actual value - Approximation = -3.254 - (-3.25) = -0.004

3) For the approximation of 17.22 as 17: - Actual value: 17.22 - Approximation: 17 - Error = Actual value - Approximation = 17.22 - 17 = 0.22

4) For the approximation of 3.14 as 3: - Actual value: 3.14 - Approximation: 3 - Error = Actual value - Approximation = 3.14 - 3 = 0.14

Errors in the Given Approximations:

1) The error in the approximation of 0.1975 as 0.198 is -0.0005. 2) The error in the approximation of -3.254 as -3.25 is -0.004. 3) The error in the approximation of 17.22 as 17 is 0.22. 4) The error in the approximation of 3.14 as 3 is 0.14.

Please note that these errors are calculated by subtracting the approximation from the actual value.
