Percentage is an important part of math and calculating figures when it comes to produce report based on collective data.

An important part of numeracy

One of the most popular means individuals use to define what is happening in our globe is percentages. They are used in the press to define unemployment rates, a wealth of statistics on health and welfare, and the distribution of public resources, such as how much is spent on education or the army compared to other nations.

In more private and immediate matters, percentages are used to tell us about credit card and loan interest rates, to clarify wage deductions, to announce rises in pensions and allowances, and, of course, to encourage us to save (or spend) cash with discount offers.

Since numeracy is about knowing mathematically associated elements of our globe, part of the learning of numeracy is to create meaningful percentages. We want to make it possible, whether in private situations or in relation to the wider community, to be able to get an accurate percentage for different scenarios.

The meaning of “percent”

Percent means "per hundred." Writing a percentage number is a way to compare the amount with 100. For instance: 42%= x+

Real fractions (or ratios) with a denominator of 100 are percentage points. By dropping the percent symbol and writing the amount over 100, any percent can be altered to an equivalent fraction. Usually, putting this fraction in the easiest terms is best.

Uses of Percentage Data

In reporting data, percentages are used because they are simpler to comprehend and compare than other kinds of fractions. Comparing 20% and 15% of the population, for instance, is much easier than presenting the same numbers as 1/5 and 3/20.

Because % always use the same base number, 100, percentages are simple and powerful. Unfortunately, many adults have obscured this fundamental knowledge of the significance of percentages due to a prevalent concern with teaching formulae rather than significance. However, we have developed a percentage calculator so we can easily get the percentages of different numbers and can solve percentage problems.

History of Word “Percentage” and Symbol “%”

Percentage is generally written as two words (per cent) in British English, although percentile and percentage are written as one word. Percentage is the most prevalent version in American English.

There was a dot in the word "per cent." in the mid-20th century, as opposed to "per cent". The "per cent." form is still in use in the extremely formal language found in certain papers such as loan contracts (especially those subject to, or motivated by, common law), as well as in the Hansard transcripts of British parliamentary trials.

The word was ascribed to the percentage of Latin per centum. Originally it’s Greek’s concept of considering values as components of one hundred. The percent (%) symbol developed from a symbol that abbreviated the percentage in Italy per cento. The form procent or prosent is used in some other languages. Some languages use both a term developed from percentage and an expression meaning the same thing in that language, e.g. Romanian procent and la sută (i.e. 10% for[ each] hundred can be read or written at times, similar to the English one out of ten).

How & Where to Use Percentage

Often, grammar and style guides vary in how to write percentages. For example, the word percent (or per cent) is commonly suggested to be spelled out in all texts, as in "1 percent" rather than "1%." Other guides prefer the word in humanistic texts to be written, but the symbol to be used in scientific texts. Most guides agree that they are always written with a number, as in' 5 percent' and not' five percent,' the only exception being at the start of a phrase:' Ten percent of all authors love custom guides.'

Decimals should be used instead of fractions, as in “3.5 percent of the profit” and not “3 1⁄2 percent of the profit.” However, government bong and other issuing titles use the fractional form, e.g. "3 1⁄2 % unsecured loan stock 2032 Series 2."

When interest rates are very low, the number 0 is included if the interest rate is less than 1 percent, e.g. “0 3⁄4 % Treasury Stock,” not “3⁄4 % Treasury Stock.” It is also widely accepted that the percentage (%) symbol should be used in tabular and graphic material.


There are 12 types percentage calculation, we will discuss 3 only:

Type AWhat number is 15% of 63?
Type BWhat percent of 42 is 21? 
Type C25 is 40% of what number?

The method we use to solve all three types of problems involves translating the sentences into equations and then solving the equations.

The following translations are used to equations:

The word is always translates to an = sign, the word of almost always means multiply, and the number we are looking for can be represented with a letter, such as n or x.

As you can see, all three types of percent problems are solved in a similar manner. We write is as =, of as ·, and what number as n. The resulting equation is then solved to obtain the answer.


Drop the percent symbol and shift the decimal point two locations to the left to make a percent to a decimal.

Examples: 25% = 0.25 | 75% = 0.75 | 6.8% = 0.068 | 0.63% = 0.0063


It can be done by moving the decimal point two locations to the right and using the percent symbol to modify a decimal to a percentage point.

Examples: 0.27= 27% | 4.89 = 489% | 0.2 = 20% | 25 = 2500%
