How to calculate the fold for a decrease?
Divide the original amount by the new amount to determine the fold change for a decrease. For instance, if you have 20 grams of water at the beginning of an experiment and end up with 4 grams, divide the original number (20) by the new (4) and note the answer as a negative result. In this case, 20/4 = -5 fold.
Which is the fold change between 30 and 60?
It is defined as the ratio between the two quantities; for quantities A and B, then the fold change of B with respect to A is B / A.
