Frequently Asked Questions
Q: How do I calculate percentage of a number?
A: To find what percentage one number is of another, divide the first number by the second and multiply by 100. For example, to find what percentage 25 is of 50: (25 ÷ 50) × 100 = 50%.
Q: Can I calculate percentage increase or decrease?
A: Yes! For percentage change, first find the difference between new and old values, then divide by old value and multiply by 100. For example, increase from 80 to 100: ((100-80) ÷ 80) × 100 = 25% increase.
Q: What if the result is more than 100%?
A: Percentages can exceed 100% when the value is greater than the total. For example, if comparing growth, 200% means the value doubled. This is common in growth rates, returns, and comparative statistics.
