The formula to calculate the fold decrease is:
\[ \text{FD} = \frac{\text{IV}}{\text{FV}} \]
Where:
Let's consider an example:
Using the formula to calculate the fold decrease:
\[ \text{FD} = \frac{1000}{100} = 10 \]
This demonstrates that the fold decrease from 1000 to 100 is 10, meaning the final value is 1/10th of the initial value. ✅
