Understanding Percentages
Percentages are a way of expressing a number as a fraction of 100. The ‘%’ symbol is used to represent percentages. For example, 50% is the same as 50 out of 100. Understanding percentages is important for a wide range of applications, from calculating discounts when shopping to understanding interest rates on loans and investments.
Calculating Percentages
When calculating percentages, it’s important to understand the basic formula:
Percent = (Part/Whole) * 100
