I am stuck on a question my professor has given me. I feel like the answer is easy and I am just overthinking things.
Question is, we are dealing with the importance of significant figures. How do I calculate the minimum and maximum error by rounding off. For example if I used 1 when the answer is 9, 10 if the answer is 99?
Is it just 1/9 x100% ? 10/99 x100% ? The percentage decreases so that part makes sense that the more sig figs the less percent error.
What do you think?
