Two-fold Decrease

 In the phrase "two-fold increase", the term "increase" refers to the very fact that one number is bigger than the opposite , not the quantity by which one is bigger than the opposite . The expansion is two-overlap on the grounds that the new number is double the old number. Fold change may be a measure describing what proportion a quantity changes between an ingenious and a subsequent measurement. 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. Fold change is usually used when analysing multiple measurements of a biological system taken at different times because the change described by the ratio between the time points is easier to interpret than the difference.Hydrogen peroxide
