Frequently Asked Questions (FAQ)

📊 How do I calculate percentage of a number?

To calculate X% of Y: Multiply the number by the percentage and divide by 100. Formula: (Percentage ÷ 100) × Number. For example, 25% of 200 = (25 ÷ 100) × 200 = 0.25 × 200 = 50.

🔍 How do I find what percent one number is of another?

To find what percent X is of Y: Divide X by Y and multiply by 100. Formula: (X ÷ Y) × 100. For example, what percent is 50 of 200? (50 ÷ 200) × 100 = 0.25 × 100 = 25%.

📈 How do I calculate percentage increase or decrease?

Percentage change = ((New Value - Old Value) ÷ Old Value) × 100. If positive, it's an increase; if negative, it's a decrease. For example, from 100 to 120: ((120-100) ÷ 100) × 100 = 20% increase.

🔄 What's the difference between percentage change and percentage difference?

Percentage change compares a new value to an original value (can be positive or negative). Percentage difference compares two values relative to their average (always positive). Use change for before/after scenarios, difference for comparing two separate values.

💡 When should I use each type of percentage calculation?

Use "% of Number" for discounts/tips, "What %" for test scores/ratios, "% Change" for growth rates/price changes, and "% Difference" for comparing two separate values like comparing salaries or comparing test scores of two students.
