Understanding the Calculation
Explanation of Percentage
Percentage is a fundamental concept in mathematics that is used to express a proportion or a fraction of a whole in terms of 100. It is commonly denoted by the symbol “%”. Understanding percentages is crucial in various aspects of life, including finance, business, and everyday calculations.
Formula for Calculating Percentage
Calculating a percentage involves a simple formula that relates the part to the whole. The formula is:
[ \text{Percentage} = \left( \frac{ \text{Part} }{ \text{Whole} } \right) \times 100 ]
This formula allows you to determine what percentage one number is of another. For example, if you want to find out what 20% of 50 is, you would plug in the values into the formula:
[ \text{Percentage} = \left( \frac{ 20 }{ 50 } \right) \times 100 = 40 \%]
By following this formula, you can easily calculate percentages in various scenarios, whether it’s for calculating discounts, interest rates, or simply understanding proportions in everyday life.
Practical Application

Therefore, 15% of $10.00 is $1.50. This calculation showcases how percentages are used in determining amounts, such as discounts or tips, based on a given percentage of a total value.
