Formula Explanation Made Simple
At the heart of percentage math is a simple relationship: Percentage × Original Value = Result. For example, to find 20% of 150, you convert 20% to a decimal (0.20) and multiply it by 150, which gives 30.
- To find a percentage of a number, convert the percentage to a decimal and multiply.
- To find what percentage one number is of another, divide the part by the whole and multiply by 100.
- For percentage change, calculate the difference between two values, then divide by the original value.
Step-by-Step Example You Can Follow
Let’s say you want to calculate 15% of 200:
- Convert 15% to a decimal: 15 ÷ 100 = 0.15
- Multiply by the original number: 0.15 × 200 = 30
- So, 15% of 200 is 30.
