Understanding Percentages
Percentages are a fundamental concept in mathematics and play a crucial role in our everyday lives. Whether we are shopping, calculating discounts, or analyzing data, understanding percentages is essential. In this section, we will delve into the definition of percentages, how they are calculated, and their significance in practical scenarios.
Definition of Percentages
Percentages are a way of expressing a fraction or a proportion out of 100. The term “percent” is derived from the Latin word “per centum,” which means “per hundred.” It is denoted by the symbol “%”. Percentages are used to compare quantities, indicate ratios, and measure changes.
Calculation of Percentages
To calculate a percentage, we divide the part by the whole and multiply the result by 100. This can be represented by the formula:
Percentage = (Part / Whole) * 100
For example, if we want to find out what percentage 25 is of 100, we divide 25 by 100 and multiply the result by 100. The calculation would be:
Percentage = (25 / 100) * 100 = 25%
