Stepwise Method to Change Percentages into Fractions
Percent and Fractions are two different ways of writing parts of a whole. For example: if we say 50 percent of 1-litre milk, it is equivalent to ½(half) of 1-litre milk.
Every percentage can be converted into its equivalent fraction. Before converting percents to fractions, we should know about percents and fractions. After that, it will be easier to convert percents to fractions.
Percent:
A percent is a number or ratio expressed as a fraction of 100. It is denoted using the sign “%”. A percentage is a dimensionless number. It has no unit of measurement. When we say "Percent" we are saying "per 100".
One percent (1%) means 1 per 100. Similarly, 25% means 25 per 100.

Here 25 % is in green colour.
Examples: Find 50% of 80.
Sol: 50% means half.
50% of 80 is 50/100 x 80 = 40
Hence 50% of 80 is 40.
Fraction:
A fraction represents part of a whole or a collection.
Suppose a number has to be divided into two parts, then it can be represented as x/2. So, the fraction here, x/2, defines 1/2th of number x.
Parts of a Fraction:
Fraction has generally two parts i.e numerator and denominator.
Suppose we write ⅘.
In a fraction, there are two numbers. One number is written above a horizontal line (i.e.4) and the other is written below it (i.e.5). The top part is known as the numerator and the bottom part is known as the denominator. The horizontal line between both the numbers is known as the fraction bar.
Examples of fraction in our daily life. When we cut an apple, an orange, or any kind of fruit, we are taking a piece of the whole. We can represent those pieces as fractions.
Convert Percents to Fractions
To convert a Percent to a Fraction follow the given steps:
Write down the percent divided by 100 write like this: Percent/100.
If the percent is not a whole number, then multiply both top and bottom by 10 for every number after the decimal point. (For example, if there is one number after the decimal, then multiply 10, if there are two then use 100, etc.)
Reduce the fraction into simplest form (i.e. try to cancel out the common factors of numerator and denominator).
Let’s understand this with an example:
Convert 15 % to a fraction.
Sol: First write down as 15/100. Here percent is a whole number. Now reduce it in simplest form
15/100 = 3/20. Hence answer is 3/20.
Percent to Fraction Calculator
To convert percent to fraction, an online calculator is available. Online calculator converts a percent to a fraction. If the percent value is greater than 100% then it is converted into a mixed number fraction. Enter percents to convert them into fractions. We can also enter a number that have decimal places as in 3.5% or 0.625%.
To convert a percent to a fraction first we need to convert the percent to a decimal then use the same procedure as converting decimal to fraction.
Let’s have a look on Percent to Fraction conversion table.
Percentage to Fraction Table
Try to remember the basic conversion table. Using this table we can convert the percentages into fractions quickly.
Note: Always remember formula Percent ( % ) = Fraction x 100. Using this formula any percentage can be converted into a fraction.
Percentage to Fraction Conversion:
Question: Convert 62.5% to a fraction.
Sol: First divide by 100. So, we can write as 62.5/100
There is 1 digit after the decimal place so multiply both top and bottom by 10. After multiplying we can write as 625/1000.
Now reduce the fraction into simplest form. Divide both numerator and denominator by 25. We can write as 25/40.
We can see that it is not in the simplest form again to divide both numerator and denominator by 5.
We can write as 5/8. Now it is in its simplest form.
Hence, 5/8 is the answer.
FAQs on Converting Percents to Fractions Made Simple
1. What are the basic steps to convert a percentage into a fraction?
To convert any percentage to a fraction, you can follow two simple steps as per the NCERT guidelines for the 2025-26 session:
- Step 1: Remove the percent sign (%) and write the number as the numerator over a denominator of 100. For example, 40% becomes 40/100.
- Step 2: Simplify the fraction by dividing both the numerator and the denominator by their greatest common factor (GCF). For 40/100, the GCF is 20, so the simplified fraction is 2/5.
2. Why is a percentage always converted to a fraction with 100 as the denominator?
The word "percent" literally means "per hundred" or "out of 100." Therefore, when you see a number with a percent sign (e.g., 25%), it represents 25 parts out of a total of 100 parts. This relationship is naturally written as a fraction with 100 as the denominator, which is 25/100, before any simplification.
3. How do you convert a decimal percentage like 12.5% into a fraction?
When converting a percentage that contains a decimal, the goal is to remove the decimal to create a valid fraction. Here is the method:
- First, write the percentage over 100: 12.5/100.
- Next, to eliminate the decimal, multiply both the numerator and the denominator by 10 (since there is one decimal place). This gives you 125/1000.
- Finally, simplify the fraction. The greatest common factor of 125 and 1000 is 125. Dividing both parts by 125 gives the final answer: 1/8.
4. What is a common mistake to avoid when converting a percent to a fraction?
A very common mistake is forgetting to simplify the fraction. For example, converting 50% to 50/100 is correct, but it is not the final answer. In mathematics, fractions should always be presented in their simplest form. You must divide both the numerator and denominator by their greatest common factor to get the final answer, which in this case would be 1/2.
5. How do you handle converting a percentage greater than 100%, like 175%, to a fraction?
The process remains the same, even for percentages over 100. These conversions result in an improper fraction (where the numerator is larger than the denominator). For 175%:
- Write it as a fraction over 100: 175/100.
- Find the greatest common factor, which is 25.
- Simplify by dividing both parts by 25: 175 ÷ 25 = 7 and 100 ÷ 25 = 4.
- The improper fraction is 7/4. This can also be expressed as a mixed number, which is 1 ¾.
6. Can you provide a real-world example where converting a percent to a fraction is useful?
Yes, converting percents to fractions is very useful in everyday life, especially for quick mental calculations. For instance, when shopping, if an item is 25% off, you can quickly convert this to the fraction 1/4. This makes it easier to calculate the discount in your head. If a ₹2000 jacket is 25% off, you instantly know the discount is 1/4 of ₹2000, which is ₹500.
7. How can you convert a repeating decimal percentage like 33.33...% into a fraction?
Percentages with repeating decimals are often equivalent to well-known fractions. It's helpful to recognise these common conversions:
- 33.33...% (or 33 ⅓%) is equivalent to the fraction 1/3.
- 66.66...% (or 66 ⅔%) is equivalent to the fraction 2/3.
- 16.66...% (or 16 ⅔%) is equivalent to the fraction 1/6.
Recognising these equivalents is much faster than going through the full conversion process for repeating decimals.
