The Basics of Percentages
Before we dive into the calculation, let's review the basics of percentages. A percentage is a fraction expressed as a part of 100. It is denoted by the symbol '%.' For example, 25% means 25 out of 100, or 0.25 as a decimal. Percentages are used to represent proportions or ratios. They are commonly used in finance, science, and everyday life.
The Formula for Calculating Percentages
To calculate a percentage, you need to use the following formula:
Percentage = (Part / Whole) x 100
The 'Part' represents the fraction you want to find the percentage of, while the 'Whole' represents the total amount. To find 25 percent of 150, we need to apply this formula.
Step-by-Step Guide to Finding 25 Percent of 150

Step 2: Multiply 0.25 by 150
The second step is to multiply the decimal equivalent of 25 percent by 150, the total amount.
0.25 x 150 = 37.5
So, 25 percent of 150 is 37.5.
