How to calculate percentage of two numbers
Calculating the percentage of two numbers is a valuable skill that can be applied in numerous academic, professional, and everyday situations. Percentages are an easy way to compare relative sizes, proportions, or growth. In this article, we will explain how to calculate the percentage of two numbers in a simple step-by-step process.
Step 1: Understand the concept of percentage
A percentage is a way of expressing a number as a fraction of 100. It is represented with the “%” symbol and essentially shows how much out of 100 a specific quantity represents. It is used in everyday life when dealing with data analysis, financial matters, sports statistics, and much more.
Step 2: Determine the part and the whole
In order to calculate a percentage, you need to know:
– The part: this is the smaller number or amount that you want to express as a percentage.
– The whole: this is the larger number or total amount that the part is being compared to.
Step 3: Divide
Divide the part (smaller number) by the whole (larger number). This will give you a decimal value that represents how much out of one (not 100) the part comprises of.
Formula: Part ÷ Whole = Decimal
Example:
If you want to know what percentage of apples in a fruit basket are green where there are 24 green apples and 40 apples overall:
Part = 24 (green apples)
Whole = 40 (total apples)
Calculate the decimal value:
Decimal = Part ÷ Whole
Decimal = 24 ÷ 40
Decimal = 0.6
Step 4: Convert decimal to percentage
To convert your decimal value into a percentage value, multiply it by 100.
Formula: Decimal × 100 = Percentage
Example:
Percentage = Decimal × 100
Percentage = 0.6 × 100
Percentage = 60%
So, the green apples make up 60% of the total apples in the fruit basket.
Conclusion:
Calculating the percentage of two numbers is a simple and useful mathematical technique that can help you understand relationships between parts and wholes. In just a few steps, you can determine what proportion one number represents out of another, equipping you with valuable information to better understand various aspects of your personal, academic, or professional life.
