Ah, math. The notoriously complex and confusing subject that has been haunting students since the beginning of time. But fear not, dear reader, for today we will be tackling a simple yet fundamental question: What is 20 percent of 64? Don’t worry, no calculators or complex formulas required. Just sit back, relax, and let’s dive into the world of percentages.
1. The Ultimate Guide to Calculating 20 Percent of 64
Have you ever found yourself in a situation where you need to calculate 20 percent of a number, but you don’t quite remember how to do it? Well, fear no more! In this guide, we will walk you through step-by-step on how to calculate 20 percent of 64.
Firstly, it’s important to understand what 20 percent means. Percent simply means “per hundred.” So, if we’re calculating 20 percent, we’re essentially finding 20 parts out of 100. To make it simpler, we can also say that 20 percent is the same as 0.2 (20 divided by 100).
Now, let’s move on to the actual calculation. To calculate 20 percent of 64, we can use the following formula:
20/100 x 64
This formula simply means that we need to multiply 20 (the percentage we want to find) by 64 (the number we want to find the percentage of) and then divide it by 100 (the total value).
So, when we plug in the numbers, we get:
20/100 x 64 = 12.8
Therefore, 20 percent of 64 is 12.8.
Another way to think about it is to simply move the decimal point of 64 one place to the left (since we’re finding 20 percent, or 20 parts out of 100) and then multiply it by 2. So, we get:
64 ÷ 10 x 2 = 12.8
Either way, we get the same answer.
Now, let’s take a look at some common uses of calculating 20 percent of a number. For example, if you’re out shopping and you see a 64-dollar item on sale for 20 percent off, you can easily calculate the sale price by subtracting 20 percent (or finding 80 percent) of the original price from the original price. So, we get:
64 – 12.8 = 51.2
Therefore, the sale price of the item is 51.2 dollars.
In conclusion, calculating 20 percent of 64 (or any other number) is a simple process that can come in handy in many situations. Whether you’re out shopping, calculating percentages for school or work, or simply trying to improve your mental math skills, this guide has hopefully helped you understand how to do it with ease.
2. Mastering the Art of Finding One-Fifth of 64
Are you looking to master the art of finding one-fifth of 64? Look no further! With a few simple steps, you can easily solve this problem.
First, it’s important to understand what “one-fifth” means. Essentially, it means dividing something into five equal parts and taking one of those parts. In this case, we’re looking for one-fifth of 64.
To calculate this, we can start by dividing 64 by 5. This gives us a result of 12.8. However, we’re looking for a whole number, so we need to round to the nearest whole number. In this case, 12 is the closest whole number.
Now that we have our result, we can confirm that 12 is indeed one-fifth of 64. How? We can multiply 12 by 5 to get back to our original number, 64. When we do this, we get:
12 x 5 = 60
Adding the remaining fifth, we have:
60 + 12 = 64
So there you have it – is as easy as dividing by 5 and rounding to the nearest whole number.
But what if you’re faced with a similar problem, such as finding one-fifth of a different number? The process is the same. Divide the number by 5, round to the nearest whole number, and multiply by 5 to confirm your result.
To make things even easier, you can memorize a few common fractions and their corresponding decimal values. For example, one-fifth is equal to 0.2, one-fourth is equal to 0.25, and one-third is equal to 0.33 (rounded to two decimal places). Having these values memorized can save time and make solving fractions a breeze.
So next time you’re faced with the challenge of finding one-fifth of a number, don’t fret. With a few simple steps and a little bit of practice, you’ll be able to master this art in no time.

The first step is to remember what 20% actually means. Percentages are simply a way of expressing a fraction of a whole, so 20% is the same as 20 divided by 100, which simplifies to 1/5. So, if we want to find 20% of 64, we can simply divide 64 by 5.
To do this, we can use a few different tricks depending on our preferences. Some people prefer to divide by 10 first and then multiply by 2, while others may find it easier to divide by 2 first and then multiply by 10. Either way, we can use a combination of division and multiplication to reach our answer.
- Divide 64 by 10 to get 6.4
- Multiply 6.4 by 2 to get 12.8
Alternatively:

4. The Easiest Method to Calculate 20 Percent of 64
Calculating percentages may seem like a daunting task, but with the right method and a bit of practice, it becomes easier over time. In this post, we will discuss the simplest way to calculate 20 percent of 64.
Firstly, it’s important to understand what a percentage is. A percentage is simply a fraction expressed as a number out of 100. For example, 20% can be written as 20/100 or 0.20 as a decimal. Now that we have this understanding, we can proceed with the calculation.
To find 20 percent of any number, we can multiply that number by 0.20. Let’s apply this to our example of 64.
64 x 0.20 = 12.8
So, 20 percent of 64 is 12.8. This means that if something costs $64 and you receive a 20% discount, you would save $12.8 and only pay $51.2.
Another method to calculate percentages is to divide the percentage by 100 and then multiply it by the number you want to find the percentage of. In this case, we can use the formula:
(20 ÷ 100) x 64 = 12.8
This formula gives us the same result as before. However, the first method of multiplying by 0.20 is simpler and easier to remember.
It’s worth noting that you can also reverse this formula to find the original amount if you only have the percentage and the final result. For example, if you know that a discount of 20% gave you a total price of $51.2, you can use the following formula:
Original amount = final amount ÷ (1 – percentage as a decimal)
With the given information, we can calculate the original amount as follows:
Original amount = 51.2 ÷ (1 – 0.20) = 64
It’s always a good idea to double-check your results or use a calculator to avoid any mistakes.
In conclusion, finding 20 percent of 64 is a simple process. You can either multiply 64 by 0.20 or use the percentage formula to get the answer 12.8. Understanding how percentages work and practicing these methods can make percentage calculations a breeze.
