Common Percentage Calculations

Finding a Percentage of a Number

To find a percentage of a number:

• Formula: ((\text{Percentage} \times \text{Number}) / 100)
• Example: What is 20% of 150?
  • Calculation: ((20 \times 150) / 100 = 30)

Calculating Percentage Increase or Decrease

To calculate the percentage increase or decrease between two numbers:

• Formula: (((\text{New Value} - \text{Old Value}) / \text{Old Value}) \times 100)
• Example: If a product price increases from $50 to $65, what is the percentage increase?
  • Calculation: (((65 - 50) / 50) \times 100 = 30\%)

Determining Percentage Change

To determine the percentage change from one value to another:

• Formula: (((\text{New Value} - \text{Old Value}) / \text{Old Value}) \times 100)
• Example: If a stock price drops from $120 to $90, what is the percentage change?
  • Calculation: (((90 - 120) / 120) \times 100 = -25\%)
