Here’s how to Convert Decimals to Percents
Converting decimals to percents is a fundamental math concept that is used in various fields such as finance, science, and engineering. Decimals are fractions expressed in the base-10 system, while percents are ratios that represent parts out of 100. Therefore, converting decimals to percents involves multiplying the decimal by 100 and adding the percent symbol.
In math, decimals are used to represent numbers that are not whole. They are written using a decimal point to separate the whole number part from the fractional part. On the other hand, percents are used to express a part of a whole, and they are always written with the percent symbol (%). Converting decimals to percents is a simple process that involves multiplying the decimal by 100 and adding the percent symbol. For instance, the decimal 0.25 is equivalent to 25% when converted to a percent.
Learning how to convert decimals to percents is essential for solving many math problems, including those that involve percentages, fractions, and ratios. It is also a crucial skill for everyday life, such as calculating discounts, taxes, and interest rates. In this article, we will explore the concept of converting decimals to percents in detail, including the steps involved, examples, and frequently asked questions.
A Decimal is a number that is less than one but greater then zero. A Percent is a number that represents how many out of 100 there are. For example, when a number is said to be 60%, it means that there are 60 out of 100 in the number. When Converting a Decimal to a Percent, you have to change the decimal into a percent by multiplying the decimal by 100. There is a shortcut for multiplying the decimal by 100. The easiest way multiply the decimal by 100 is to move the decimal place to the right two times. This is the same as multiplying the number by 100 except that you do not have to do any math. Another way of thinking when converting decimals to a percents move the decimal two places to the right. Once the decimal has been converted to a percent, you can add your percentage sign to show that it is now a percent.

3 Easy Methods for Converting Decimals to Percents
When working with numbers, it is often necessary to convert decimals to percents. This can be done in a few different ways, depending on the situation. In this section, we will explore three methods for converting decimals to percents.
Method 1: Multiply by 100%
One way to convert a decimal to a percent is to multiply it by 100%. For example, to convert 0.75 to a percent, you would multiply by 100%:
0.75 x 100% = 75%
This method works well when the decimal is less than 1. If the decimal is greater than 1, it will result in a percent greater than 100%.
Method 2: Move the Decimal Point
Another way to convert a decimal to a percent is to move the decimal point two places to the right and add a percent sign. For example, to convert 0.35 to a percent, you would move the decimal point two places to the right:
0.35 = 35%
This method is useful when the decimal has one’s place only, or when it is easy to mentally move the decimal point.
Method 3: Convert to Fraction First
A third method for converting decimals to percents is to convert the decimal to a fraction first, and then convert the fraction to a percent. To convert a decimal to a fraction, we place the decimal over a denominator of 1 followed by as many zeroes as there are digits after the decimal point. For example:
0.6 = 6/10 = 3/5
To convert the fraction to a percent, we multiply by 100%. For example:
3/5 x 100% = 60%
This method is useful when the decimal has a repeating pattern or when it is easier to work with fractions than decimals.
In conclusion, there are several methods for converting decimals to percents, including multiplying by 100%, moving the decimal point, and converting to a fraction first. By using these methods, one can quickly and accurately convert decimals to percents.
Decimal Definition in Math
Understanding Decimals and Percents
Decimals are a way of representing numbers that fall between two whole numbers. They are a part of the base-ten number system and are used to represent fractions of a whole number. A decimal point separates the whole number from the fractional part, which is expressed in tenths, hundredths, thousandths, and so on. For example, 0.5 represents half of a whole number, 0.25 represents a quarter, and 0.75 represents three-quarters.
Percents, on the other hand, are a way of expressing a proportion as a fraction of 100. They are represented by the symbol “%”. For example, 50% represents half of a whole, 25% represents a quarter, and 75% represents three-quarters.
Definition of Percents
In mathematics, percent is a ratio that expresses a number as a fraction of 100. The word “percent” is derived from the Latin word “per centum,” which means “by the hundred.” For example, 50% is equivalent to the fraction 50/100, which can be simplified to 1/2. Percentages are commonly used in everyday life, such as calculating discounts, taxes, and tips.
Relationship Between Decimals and Percents
Decimals and percents are related to each other in that they can be converted from one form to another. To convert a decimal to a percent, the decimal is multiplied by 100 and the “%” symbol is added. For example, 0.5 can be converted to 50%. To convert a percent to a decimal, the percent is divided by 100. For example, 50% can be converted to 0.5.
| Decimal | Percent |
|---|---|
| 0.1 | 10% |
| 0.25 | 25% |
| 0.5 | 50% |
| 0.75 | 75% |
| 1.0 | 100% |
Understanding the relationship between decimals and percents is important in many areas of mathematics, such as algebra, geometry, and statistics. It is also useful in everyday life, such as calculating interest rates, discounts, and sales tax.

A decimal is any number that is less than one but greater than zero. A percentage is a number that represents how many out of one hundred there are. If we said something was 30 that means that 30 out of 100 would be included in the number. Now because a percent is out of 100 the way you can convert from a decimal to a percent is to multiply times 100. In other words, when converting decimals to a percents move the decimal point two times to the right.
This example gives us a decimal point of 0.29. For this decimal converting to percent we’re going to take 0.29 and multiply times 100. 0.29 times 100 is going to be 29 or 29. Now a shortcut for converting decimals to percents is to take your decimal and move the decimal point two times to the right. We take the decimal point move it twice to the right. In the case of the 0.29 decimal, we’ll leave the decimal point behind the 9 and it will change to a 29. Now the shortcut of moving the decimal two times to the right is because you’re multiplying times 100 and when you multiply by 100 because 100 has two zeros. The zeros are going to move the decimal point to the right two times, one time for each zero. The shortcut for converting decimals to percents is to just move the decimal two times to the right. Let’s do a couple practice problems about how to convert decimals into percents.
The first problem on our changing decimals to percents worksheet gives us 0.65. Now we know in order to convert a decimal to a percentage we have to multiply our decimal times 100. When we multiply the decimal times 100 the decimal point is going to move one two times to the right. In the case of 0.65 it’s going to turn into 65 and we know that it’s going to be 65 percent. We could also use the shortcut of taking our decimal point and moving it to the right two times to give us our percent which is going to be 65 percent as well.
The last problem we’re going to complete on our changing decimals to percents worksheet is number five. This problem gives us 1.75 as our decimal point. In order to convert that to a percent we’re going to multiply times 100. When we do that the decimal point moves two times to the right because of each zero and 100 we get our whole number of 175. And I know that’s a percent because we multiplied times 100. 1.75 as a percentage is 175 percent. We could also follow the shortcut of just taking our decimal point and moving it two times to the right to get a whole number. It’s going to be 175 and I know that it’s a percent because we multiply times 100. When converting decimals to percents it doesn’t matter if you multiply by 100 or if you just move the decimal two times to the right, you’re going to get the same solution. I hope this video was helpful for teaching you how to convert decimals to percents.
