In many facets of life, especially in the banking, admissions, school test, and competitive evaluations like the International Mathematical Olympiad (IMO), percentage math is essential. Comprehending percentages and being proficient in shortcut techniques not only streamlines computations but also improves problem-solving accuracy and efficiency. We will discuss the relevance of percentage math in various areas in this succinct introduction, and we will emphasize the value of shortcuts in overcoming numerical difficulties.
Here, we uploaded 3 videos for different percentage math problems. If anyone will learn and follow steps of those 3 videos, everyone can solve percentage math like a genius. Let’s first discuss the step by step for percentage math problems.
Calculating percentages involves finding a portion of a whole number, often expressed as a fraction of 100. Here’s a step-by-step guide on how to do percentage math:
Understand the Concept: Percentages represent parts of a whole. For example, if you have 25% of something, you have 25 out of 100 parts of the whole.
Convert the Percentage to a Decimal: To begin, convert the percentage to a decimal by dividing it by 100. For example, 25% becomes 0.25, 50% becomes 0.50, and so on.
Determine the Whole Number: Identify the whole number or quantity that you want to find the percentage of. For instance, if you want to find 25% of 200, then 200 is your whole number.
Calculate the Percentage: multiply the percentage’s decimal representation by the total number. This provides you with the percentage-represented piece or fraction of the whole.
Interpret the Result: The result of the calculation represents the portion of the whole that the percentage represents. In this example, 25% of 200 is 50, meaning that 50 is 25% of 200.
Check Your Work: To ensure accuracy, it’s a good practice to double-check your work after computing the percentage. This can be accomplished by confirming that the value you obtained is equal to the percentage multiplied by the whole number.
Express as a Percentage: If necessary, you can express the result as a percentage by multiplying the decimal by 100. This step is useful when converting from a decimal back to a percentage.
By following these steps, you can confidently calculate percentages for various applications, such as discounts, markups, proportions, and many others. In this video, we discuss one type of percentage math. For example- What percent of 20 is 80? What percent of 75 is 15? – Let’s learn this kind of math tricks.
Now, let’s see another short cut tricks for solving percentage math in a short cut way.
Sometimes, you will see in exam, some question will ask what percentage of any number. For example- what is 9% of 205. So, actually we need to find out when 205 is 9% what is the answer of this type of math. Many students are struggling those kind of math questions, but after watching this video, everyone can be able to solve those kind of math problems within a few seconds. So, Let’s check our video-
Always remember, practice makes perfect, so keep practicing strengthening your percentage calculation skills.
