1. Simple Percentage Calculations
To compute a fixed percentage out of a base value, use this baseline algebraic formula:
Formula: $\text{Value} = \left(\frac{\text{Percentage}}{100}\right) \times \text{Base Amount}$
2. Percentage Ratios and Grades
To solve what percent a smaller number is of a major numerical total (useful for checking school exam marks), apply this formula:
Formula: $\text{Percentage} = \left(\frac{\text{Part}}{\text{Total}}\right) \times 100$
3. Measuring Market Growth (Increase / Decrease)
Analyzing stock market growth or corporate profit loss relies heavily on measuring shifts between an old baseline and a new milestone:
Formula: $\text{Shift Percentage} = \left(\frac{\text{New Value} - \text{Old Value}}{\text{Old Value}}\right) \times 100$
