# How to Quickly Calculate Percentages between Two Numbers

175 You can calculate percentages differently, but we’ll focus on the three most common methods.

## 1) Decimal Method:

First, let’s look at how to calculate percentages using decimals. To do this, simply follow these steps:

1. Convert it into a decimal by moving the point two places to your left. For example, if we calculate 20%, we would convert it to 0.20.

2. Multiply the decimal by the whole number. So, if we’re calculating 20% of 100, we would multiply 0.20 by 100 to get 20.

3. To find the percentage of a specific number between two other numbers (like finding 20% of 75), first convert the percentage into a decimal and then multiply it by the number in question (in this case, 75). Then, divide that answer by the second number (in our example, 100). The equation would look like this: (0.20*75)/100=15. So, 20% of 75 is equal to 15.

## 2) Fraction Method:

Now let’s take a look at how to calculate percentages using fractions. This method is a little bit simpler; just follow these steps:

1. Convert the percentage into a fraction by removing the percent sign and placing it over 100. So, 20% would become 20/100.

2. Multiply the fraction by the whole number. So, if we’re calculating 20% of 100, we would multiply 20/100 by 100 to get 20/100 * 100/100=20/100 * 1=20/1=20.

3. To find the percentage of a specific number between two other numbers (like finding 20% of 75), first convert the percentage into a fraction and then multiply it by the number in question (in this case, 75). Then divide that answer by the second number (in our example, 100). The equation would look like this: (20/100)*75)/(100)=15/(100)=0.15 . So,20% of 75 is equal to 0 .15, which is equivalent to 15%.

## 3) Ratio Method

This is the most common method used to calculate percentages. Here’s how it works:

1. Express the percentage as a ratio. So, if we’re calculating 50%, we would write it as 50:100.

2. Convert the ratio into a fraction by placing a colon between the two numbers and simplifying. So, 50:100 would become 50/100.

3. Multiply the fraction by the whole number. So, if we’re calculating 50% of 100, we would multiply 50/100 by 100 to get 50.

4. To find the percentage of a specific number between two other numbers (like finding 50% of 75), first convert the percentage into a fraction and then multiply it by the number in question (in this case, 75). Then divide that answer by the second number (in our example, 100). The equation would look like this: (50/100)*75)/(100)=37.5/(100)=0.375 . So, 50% of 75 is equal to 0.375, which is equivalent to 37.5%.

Conclusion:

As you can see, there are two ways to calculate percentages between two numbers—using decimals or fractions. Both methods are pretty simple once you get the hang of them, so practice until you feel confident in your abilities!
