Percentages are very popular since they can describe situations that involve large numbers (e.g., estimating chances for winning the lottery), averages (e.g., determining the final grade of your course), as well as very small ones (like the volumetric proportion of NO₂ in the air, also frequently expressed by PPM - parts per million). Percentage is one of many ways to express a dimensionless relation between two numbers (the other methods being ratios and fractions). Keep reading if you would like to see how to find a percentage of something, what the percentage formula is, and the applications of percentages in other areas of life, like statistics or physics.
