To calculate percentages, start by writing the number you want to turn into a percentage over the total value so you end up with a fraction. Then, turn the fraction into a decimal by dividing the top number by the bottom number. Finally, multiply the decimal by 100 to find the percentage.


As a number, 100 is very convenient compared with varying fractions. You can divide evenly it by 1, 2, 4, 5, and 10, which are easy numbers to remember. But notice that it isn’t divisible by 3, 6, 7, and 9. Once you convert them, you encounter the awkwardness of repeating decimals. Rounded off to 4 decimal places, 100/3 is 33.3333(…).

It is forgivable to assume that the percentage sign "%" depicts a fraction. It does look like one at first glance, as does the division symbol, the obelus (÷). You may also question why the symbol has two zeroes in it. After all, isn’t dividing by zero undefined? Some sources claim that the two circles represent a shorthand for one hundred. That, while sort-of true, is not the whole story. The story behind it is much more complex. (Source: www.calculators.org)


The percentage increase calculator above computes an increase or decrease of a specific percentage of the input number. It basically involves converting a percent into its decimal equivalent, and either subtracting (decrease) or adding (increase) the decimal equivalent from and to 1, respectively. Multiplying the original number by this value will result in either an increase or decrease of the number by the given percent. Refer to the example below for clarification.

In its most literal form, percentages mean “part per hundred.” This is the expression of a fraction or ratio where the denominator is 100. The percentage became one of the most popular expressions of fractions for a reason. They illustrate proportion and completeness in a way that’s easy to understand. They also simplify the process of calculating based on a proportion. Percentages convert to decimals, which are much easier to process. (Source: www.calculators.org)


We might not notice it, but percentages are quite common in daily life. Even if your work does not involve a lot of computing or mathematical concepts, you’re bound to encounter it now and then. For instance, when you check your mobile phone, its battery life is expressed in percent. A retail store is offering up to 50% off on jeans till the end of the month. When you catch the news, the weather anchor says there’s 30% chance of rain in your area.

Both percentages and fractions are ways to describe ratio. Ratio can be defined as the numerical relation between two figures which shows the number of times one value is contained within the other. To help you visualize it better, imagine a whole box broken into 100 equal parts, where each part is equivalent to a single percent. (Source: www.calculators.org)
