Mastering Percentages in English: A Step-by-Step Guide
Making calculations involving percentages may seem daunting at first, but it is actually quite simple. Percentages are used in a variety of contexts like calculating discounts, taxes, and interest rates. Whether you are a student, business owner, or simply someone who wants to brush up on their math skills, knowing how to calculate percentages is essential. In this article, we will guide you through the step-by-step process of calculating percentages in relaxed English language.
To begin, it is important to understand that a percentage is a way of expressing a fraction out of 100. For example, 50% means “50 out of 100” or simply “half”. As such, when calculating a percentage, you are essentially finding what fraction of a total amount a specific number represents. With a little bit of practice and some helpful tips, you can easily master the art of calculating percentages. In the following sections, we will explore the different methods of calculating percentages, including using a calculator, a percentage chart, and mental math. So, let’s get started!
Introduction:
In this article, we will guide you on how to make percentage easily. Whether you’re a student, a business owner, or just curious about what percentage is and how it works, we’ve got you covered. So, let’s dive in!
Section 1: Understanding the Concept of Percentage
What is percentage and how does it work?
Percentage is a fraction of 100. It is a way of representing a part of a whole in terms of a fraction of 100. For example, if we say that 50% of the employees in a company are women, it means that out of all the employees in that company, half of them are women. In mathematical terms, percentage is expressed as a number followed by the symbol ‘%’. To calculate the percentage of a number, we divide the part by the whole and then multiply by 100.
Why is percentage important?
Percentage is an important concept in many fields, including finance, economics, mathematics, and science. It helps us to understand and analyze data in a more meaningful way. For example, in finance, percentage is used to calculate interest rates, discounts, and markups. Similarly, in science, percentage is used to represent concentrations, proportions, and growth rates.
Types of Percentage
There are three types of percentage; these are increase, decrease, and finding a percentage of a number. Increase percentage is used to show the amount of increase between two numbers. Decrease percentage is used to indicate the reduction between two numbers. Finding a percentage of a number is used to find what percentage a certain value is of another value.
Section 2: Calculating Percentage
How to find the percentage of a number?
Suppose we want to find out what percentage 20 is of 100. We can use the following formula:
Percentage = (Part / Whole) x 100
In this case, Part = 20 and Whole = 100. So, we get:
Percentage = (20 / 100) x 100 = 20%
Therefore, 20 is 20% of 100.
How to find the part when the percentage and the whole are known?
Suppose we want to find out what part of 100 is 20%. We can use the following formula:
Part = (Percentage x Whole) / 100
In this case, Percentage = 20 and Whole = 100. So, we get:
Part = (20 x 100) / 100 = 20
Therefore, 20 is the part of 100 when the percentage is 20%.
How to find the whole when the part and the percentage are known?
Suppose we want to find out what number is 20% of 50. We can use the following formula:
Whole = (Part / Percentage) x 100
In this case, Part = 20 and Percentage = 50. So, we get:
Whole = (20 / 50) x 100 = 40
Therefore, 40 is the whole when the part is 20% of 50.
Section 3: Applications of Percentage
Percentage in Business and Economics
Percentage is widely used in the business and economics world. It is used to calculate profits, expenses, taxes, and other financial figures. For example, businesses use percentage to calculate their profit margins, which is the percentage of profit earned on each sale. Government agencies also use percentage to calculate taxes, such as sales tax, income tax, and property tax.
Percentage in Sports and Entertainment
Percentage is also used in sports and entertainment industries. For example, the percentage of passes a quarterback completes in a football game, the percentage of shots a basketball player makes from the free-throw line, the percentage of completion of a movie, and the percentage of returns a tennis player makes are all relevant percentages in their respective fields.
Percentage in Science and Medicine
In science and medicine, percentage is used to represent concentrations, proportions, and growth rates. For example, blood sugar and cholesterol levels are often given in terms of percentages. Likewise, in medical research, the percentage of people who respond positively to a treatment is an important figure in determining the effectiveness of the treatment.
Conclusion:
In conclusion, percentage is an important concept that has many applications in various fields. Understanding how to calculate percentage and how to interpret percentage values is essential for making informed decisions and interpreting data accurately. We hope that this article has provided you with a solid foundation in understanding how to make percentage.

How to Calculate Percentage of a Number
Calculating percentages is a fundamental mathematical skill that finds its application in numerous aspects of life. Knowing how to calculate percentages is essential for daily tasks such as managing finances, analyzing trends, and evaluating quantitative data. In this section, we’ll dive into the step-by-step process of calculating percentages of a number.
Understanding Percentages
Before we jump into calculating percentages, it’s important to have a solid understanding of what percentages are. Percentages are a representation of a portion of a whole in terms of 100. For example, if we say that 25% of a class scored A’s, it means that 25 out of 100 students achieved an A grade. In mathematics, the symbol “%” denotes percentages.
The Basic Formula
The basic formula for calculating percentages is straightforward. To calculate the percentage of a number, we multiply the number by the percentage and then divide the result by 100. The formula can be expressed mathematically as follows:
Percentage = (Number x Percentage) / 100
Let’s say we want to calculate 15% of 200. Using the formula, we can calculate it as:
Percentage = (200 x 15) / 100 = 30
Therefore, 15% of 200 is 30.
Calculating Percentage Increase or Decrease
Percentage change is a common concept in finance and economics. It refers to the difference in percentage between two values. If the percentage change is negative, it indicates a decrease, and if it’s positive, it indicates an increase. The formula to calculate percentage increase or decrease is:
Percentage Change = ((New Value – Old Value) / Old Value) x 100
Suppose we want to calculate the percentage increase if the price of a product increased from $50 to $75. Using the formula, we get:
Percentage Change = ((75 – 50) / 50) x 100 = 50%
Therefore, the price of the product increased by 50%.
Calculating Percentage of a Total
Calculating the percentage of a total involves finding the percentage that a specific value contributes to the total value. The formula to calculate the percentage of a total is:
Percentage of a Total = (Value / Total Value) x 100
Suppose we want to calculate the percentage of women in a workforce of 500 employees. If 200 of them are women, we can calculate it as:
Percentage of Women in Workforce = (200 / 500) x 100 = 40%
Therefore, women make up 40% of the workforce.
Using Tables to Calculate Percentages
Tables are an excellent tool to calculate percentages. They can be useful when dealing with large datasets. Tables can also help in visualizing the data and identifying trends.
For example, consider a table that shows the percentage of students who scored different grades in a class. The table can be used to calculate the percentage of students who achieved an A grade. Suppose the table looks like this:
Grades | Percentage of Students |
---|---|
A | 25% |
B | 35% |
C | 20% |
D | 10% |
F | 10% |
We can see that 25% of students scored an A grade. Therefore, the percentage of students who scored an A grade is 25%.
In conclusion, calculating percentages is a critical skill that’s used extensively in various fields. Understanding the formula, the percentage changes, the percentage of a total, and using tables can assist in calculating percentages with ease. By mastering this skill, you can make better-informed decisions and accurately analyze quantitative data.
