Understanding Percentages
Percentages are a way of expressing a number as a fraction of 100. It is a useful way of comparing two or more values, especially when dealing with large numbers. For example, when comparing the population of two countries, it is easier to say that one country has a population that is 50% larger than the other, rather than saying that one country has a population of 200 million and the other has a population of 133 million.
To calculate a percentage, you need to divide the part by the whole and then multiply the result by 100. For example, if you want to find out what percentage of a pizza has been eaten, you would divide the number of slices eaten by the total number of slices and then multiply the result by 100. If you have eaten 4 slices out of a total of 8, the calculation would be (4/8) x 100 = 50%.
Percentages are used in many different areas of life, including finance, science, and sports. In finance, percentages are used to calculate interest rates, stock prices, and inflation rates. In science, percentages are used to express the concentration of a solution or the success rate of an experiment. In sports, percentages are used to calculate a player’s shooting percentage or a team’s win-loss record.
It is important to understand percentages because they are used in many different contexts and can help you make informed decisions. For example, if you are shopping and you see a sale sign that says “50% off,” you know that the item is half the original price. Understanding percentages can also help you calculate discounts, taxes, and tips when dining out or shopping.

Manual Calculation of Percentages
Formula for Percent Calculation
To manually calculate percentages, you need to know the formula, which is:
Percentage = (Part / Whole) x 100%
This formula tells you what percentage the part is of the whole. The part is the amount you want to find the percentage of, and the whole is the total amount.
Step-by-Step Calculation
To calculate a percentage manually, follow these steps:
-
Identify the part and the whole: Determine the amount that represents the part and the total amount that represents the whole.
-
Divide the part by the whole: Divide the part by the whole to get a decimal number.
-
Multiply by 100: Multiply the decimal number by 100 to get the percentage.
For example, if you want to find out what percentage 25 is of 100, follow these steps:
-
Identify the part and the whole: In this case, the part is 25 and the whole is 100.
-
Divide the part by the whole: 25 ÷ 100 = 0.25.
-
Multiply by 100: 0.25 x 100 = 25%.
Therefore, 25 is 25% of 100.
Using this formula and these steps, you can manually calculate percentages for any situation. However, if you find yourself needing to calculate percentages frequently, it may be more convenient to use a percent calculator.
