Percentage Calculator (%)

Percentage calculations description:

Percentage calculations are a way to express a number as a fraction of 100. To calculate a percentage, you first determine the total amount or whole, and then divide the part you are interested in by the total and multiply by 100. The resulting number represents the percentage of the whole that the part represents.

For example, if you wanted to calculate the percentage of a test that a student got correct, you would divide the number of questions they got right by the total number of questions on the test and then multiply by 100.

There are also a few common percentage calculations that are used frequently, such as:

Finding an increase or decrease in a value: (New value – Original value) / Original value * 100
Finding the percentage of a value: (Part value / Total value) * 100
Finding the original value from a percentage: (Percentage value * Total value) / 100
It’s also important to note that percentages can be added and subtracted just like whole numbers. For example, if a store has a 20% off sale and then another 10% off sale, the total discount is 20+10 = 30%.

Percentage calculations can be a useful tool for comparing quantities and measuring change, whether in business, finance, or everyday life. It’s also important to note that percentages can be used in various situations such as calculating the percentage of a number, calculating the percentage increase or decrease, and calculating the original value from a percentage.
