What is percentage?
In a nutshell, percentage is a value represented as a fraction of 100. Hence, the name, which comes from the Latin 'per centum' and means 'per hundred'. The percentage symbol is the %.
We use the percentage to represent the proportion of a whole evaluated as a hundred. For example, if the whole is 10, it means that 10 is 100% (one hundred percent), so half or 50% (fifty percent) is 5.
The percentage is widely used in our day-to-day. With it, we evaluate growth and decrease of prices, shares, salaries, statistics and much more.

Frequently asked questions about the subject
How do I calculate a percentage?
To calculate a percentage, you need to divide the value you want to find the percentage of by the total and then multiply by 100. For example, if you want to calculate 20% of 100, you would perform the following operation: 20/100 x 100 = 20.
How can I use percentages in my daily life?
Percentages are widely used in various situations, such as in discounted purchases, interest calculations, rate calculations, and more.
How can I calculate the original value of a product with a discount?
To calculate the original value of a product with a discount, simply divide the discounted value by the discount percentage and multiply by 100. For example, if a product costs $80 with a 20% discount, the original value would be calculated as follows: 80 / (100 - 20) x 100 = $100.
How do I calculate the percentage change between two values?
To calculate the percentage change between two values, divide the difference between the values by the original value and then multiply by 100. For example, if a product was originally priced at $100 and now costs $80, the percentage change would be calculated as follows: (100 - 80) / 100 x 100 = 20%.
How can I calculate the percentage increase of a value?
To calculate the percentage increase of a value, divide the difference between the current value and the original value by the original value and then multiply by 100. For example, if a product originally cost $100 and now costs $120, the percentage increase would be calculated as follows: (120 - 100) / 100 x 100 = 20%.
