Percent Difference w/o A: How to Calculate

[badtwistoffate]

Which is ABS( A - B) / A * 100% = ANS
Anyway to do it without A? My proff says we should know it or be able to figure it out?

I'm not sure I understand the question, because it looks like your 'proff' is pulling your leg.

When you calculate a percent difference, you're determining by what ratio one thing differs from another. I don't see any way to make that determination if you're missing one of the "things". It would be like saying "an elephant is how much bigger?" Unless you know "than what", there's not much you can say.

Is it possible you misunderstood what you were supposed to do? Do you have it written down anywhere?

There is no way to accurately calculate the percent difference without knowing the value of A. The formula provided, ABS( A - B) / A * 100%, relies on the value of A in order to determine the percentage difference between A and B. It is important for scientists to have a thorough understanding of the variables and equations involved in their research, and being able to calculate the percent difference with the value of A is a crucial aspect of this understanding. If there is any uncertainty or difficulty in obtaining the value of A, it is important to address this issue and find a solution in order to accurately calculate the percent difference.
