The equation to convert a decimal to a percentage is easy, you just multiply the number by 100 and add the % sign.
Convert From Decimal To Percent
We express the percentage 0.35 by multiplying 0.35 by 100/100=1 To do this, we can use the trick described above and move the decimal point two places to the right.
Decimals To Percents Worksheet
We express the percentage 0.125 by multiplying 0.125 by 100/100=1 To do this, we can use the trick described above and move the decimal point two places to the right. Decimal to percentage conversion is one of the most important calculations in business arithmetic and banking calculations. A decimal value can be converted to a percentage value by multiplying it by 100 followed by a percent (%) sign. Multiplying decimals moves the decimal point two places to the right. For example, 0.01 is 1%. Let’s learn more about percent to decimal in this article.
Before learning about decimal to percent conversion, let’s first understand the meaning of decimal and percent. The word “decimal” comes from the Latin word decimus, meaning tenth part. The base of the decimal system is 10. Decimal numbers are usually marked with a “” dot. “decimal point” between digits. An integer can also be represented as a decimal by writing a 0 after the digit in one place with a decimal point. Example: 45 = 45.0 = 45.00 = 45.000 So. Here they are all equal to 0. There is no value after the decimal point.
The word “percentage” is derived from the two words ‘per’ and ‘percentage’, meaning “out of 100”. In other words, we can say that the ratio of 100 percent has been calculated. So, decimal to percent conversion means converting a decimal number to a fraction of 100. Step-by-step with well-illustrated real-life examples.
Decimals and percentages are two ways of expressing any number but since the base value is always hundred, percentages are used to compare different quantities. For example, the decimal values of 0.2, 0.35 and 0.1234 when converted to percentages are 20%, 35% and 12.34% respectively. Now we can easily evaluate percentage values. Let’s take a look at the following two quick steps to convert decimals to percentages.
Convert 20% Percent To Decimal And Fraction
So, we have 0.43 = 0.43 x 100% = 43%. Thus we have seen how to convert decimals to percentages. We can convert a percent to a decimal, convert it to a fraction form and then rewrite it as a decimal. Example: 45% = 45/100 = 0.45.
You can also learn about Decimal to Fraction, Fraction to Percent and Percent to Fraction to get a complete understanding of these 3 concepts.
A decimal to percent chart helps you quickly find percent values of some commonly used decimal numbers. You can use these values in calculations involving decimals and percentages.
By indulging in rote learning, you tend to forget concepts. Plus, you’ll learn visually and be amazed at the results.
Stage 7/8 Walt: Convert Fractions, Decimals And Percentages.
Decimal to percent conversion is very important to learn, because sometimes numbers are expressed as a decimal and a percent in the same equation. Therefore, to compare them or perform any operation on them, it is necessary to convert decimals to percentages or vice versa. Decimal to percent conversion is done by multiplying the decimal number by 100 and adding the percent sign to the answer.
The process of converting a decimal to a percentage value is very simple. Multiply the decimal number by 100 and add a % sign. Let’s understand this with an example. Let’s convert 4.837 to a percentage. For the calculation we have, 4.837 = 4.837 x 100% = 483.7%.
Repeating decimals can be converted to percentages simply by multiplying by 100 and applying the % sign. A repeating decimal of 0.3333 can be converted to a decimal by multiplying by 100. Here we have 0.3333… = 0.3333… x 100% = 33.33….% or approximately 33.33%.
If a fraction is given and we need to convert it to decimal and then to percentage, we follow the given steps. Divide the number by the denominator to express the fraction as a decimal, and then multiply the decimal by 100 to convert it to a percentage. This is how we convert a fraction from a decimal to a percentage. For example, given 3/4, its decimal representation is 0.75 (3 ÷ 4). Now, to convert it to a percentage, multiply it by 100 and add a percent sign. So, (0.75 × 100) % = 75%.

To convert 0.006 to a percentage, multiply it by 100 and prefix it with a percent (%) sign. Here 0.006 = 0.006 x 100% = 0.6%.
We need to convert decimals to percentages for the purpose of comparing quantities. For example, if we are given the decimals 0.06, 0.32, 0.893, we will not be able to make sense of the values. Also, if these decimals are converted into percentages like 6%, 32%, 89.3%, we can understand the quantity easily. Also, percentages provide values on a simple linear scale of 100. Today we explore the relationship between decimals, fractions and percentages. We’ll talk about how to use these numbers in the real world.
Before we begin, let’s review a few things. First, a decimal is a number that has a whole number part and a fractional part. Separating these parts is a dot called a decimal point. Digits after the decimal point represent a value less than 1.
For example, in the number 25.16, 25 is part of the whole number and the partial part is .16, which comes after the decimal point. In the number 0.75, the whole number part is 0 and the partial part is .75. 0.75 is a decimal less than 1.
Converting Fractions Into Decimals Into Percents & Vice Versa
Decimals are based on powers of 10. As we move from left to right, each position value is divided by 10:
The decimal 5.25 is read as “five and twenty five hundredths”. Because 25 comes after the decimal point, it is a fractional part of the number. We say “twenty-five hundredths” because the last digit, 5, is in hundredths.
The decimal 0.875 is read as “eight hundred and fifty thousand” because the last digit, 5, is in the thousandths place.
Because decimals have fractional parts, they can also be written as fractions. Converting a decimal to a fraction is a different way of expressing the same number. To convert a decimal to a fraction, write the numbers after the decimal point as the numerator and the place value as the denominator.
Converting Decimals To Fractions And Percentages (video & Practice)
For example, in the number 0.7, there is a 7 in the tenth place. First, write the number after the decimal point as a factor of the fraction: (frac). Next, look at the place value of the last digit in the decimal. Since 7 is a single decimal digit and is in the tenths place, write 10 as the denominator of the fraction: (frac).
0.6 in number, six tenths. The numerator is six, and each is ten, so the fraction is (frac). We can simplify (frac) by dividing the numerator and denominator by 2 to get (frac). The original fraction, (frac) is called the decimal fraction and the simplified fraction, (frac) is called the common fraction.
Let us consider another example. Let’s convert 0.25 to a fraction. First, write the numbers after the decimal point, 25, as a factor in the fraction: (frac)
Next, look at the place value of Figure 5. Since 5 is in the hundredths place, write 100 as the denominator of the fraction: (frac).

The final step is to simplify the part if needed. Since 25 and 100 share a common factor of 25, we can simplify fractions by dividing the numerator and denominator by 25: (frac=frac).
