Frequently Asked Questions (FAQs)
1. How do I calculate a percentage manually?
To calculate X% of Y manually, use this formula: (X / 100) × Y. For example, to calculate 20% of 150: (20 / 100) × 150 = 30.
2. How can I calculate what percent one number is of another?
Use this formula: (Part ÷ Whole) × 100. Example: What percent is 30 of 120? (30 / 120) × 100 = 25%.
