Finding the Error in the Given Approximations

To find the error in the given approximations, we need to compare the given numbers with their respective approximations. Let's analyze each case separately:

1) For the number 0.1975, the approximation given is 0.198. To find the error, we subtract the approximation from the actual number:

Error = Actual Number - Approximation = 0.1975 - 0.198 = -0.0005

Therefore, the error in this approximation is -0.0005.

2) For the number -3.254, the approximation given is -3.25. Again, we subtract the approximation from the actual number to find the error:

Error = Actual Number - Approximation = -3.254 - (-3.25) = -0.004

So, the error in this approximation is -0.004.

3) For the number 17.22, the approximation given is 17.4. We calculate the error as follows:

Error = Actual Number - Approximation = 17.22 - 17.4 = -0.18

Hence, the error in this approximation is -0.18.

4) For the number 3.14, the approximation given is 7.2. Let's calculate the error:

Error = Actual Number - Approximation = 3.14 - 7.2 = -4.06

Therefore, the error in this approximation is -4.06.

In summary, the errors in the given approximations are as follows: 1) Error in the approximation 0.198 for the number 0.1975: -0.0005 2) Error in the approximation -3.25 for the number -3.254: -0.004 3) Error in the approximation 17.4 for the number 17.22: -0.18 4) Error in the approximation 7.2 for the number 3.14: -4.06

I hope this helps! Let me know if you have any further questions.
