What is Percentage?

A percentage represents a portion of a whole, expressed as a fraction of 100. For example, when we say 15 percent, we are referring to 15 parts out of every 100. Percentages are widely used in various fields, including finance, education, and statistics. Understanding how to interpret and calculate percentages is crucial for making informed decisions.

In this formula, the "Part" represents the value we are calculating, while the "Whole" is the total amount. To find a specific percentage of a number, you can also use the following steps:

1. Convert the percentage to a decimal by dividing by 100 (e.g., 15% becomes 0.15).
2. Multiply the decimal by the total number (e.g., 0.15 × 84).

Calculating 15 Percent of 84

Now that we understand the concept and formula for calculating percentages, let’s apply it to find 15 percent of 84.

Using the method described:

1. Convert 15% to a decimal: 15 ÷ 100 = 0.15.
