Finding the percent of a number is a fundamental skill that is useful in various real-life situations, from calculating discounts while shopping to understanding statistics in school. In this easy practice guide, we will break down the steps on how to find the percent of a number and provide a worksheet for hands-on practice. Let's dive in! 📊
Understanding Percentages
What is a Percent?
A percent is a way to express a number as a fraction of 100. The word "percent" literally means "per hundred." For example, 45% means 45 out of 100. Knowing this, we can easily calculate how much a certain percentage of a number is by using a simple formula.
The Basic Formula
To find the percent of a number, you can use the following formula:
Percent (%) = (Part / Whole) × 100
Where:
- Part is the portion of the whole you're interested in.
- Whole is the total or complete amount.
Finding the Percent of a Number
To find a specific percent of a number, follow these steps:
- Convert the percentage into a decimal: Divide the percentage by 100. For example, to find 25%, convert it to a decimal: 25% = 0.25.
- Multiply the decimal by the number: If you want to find 25% of 200, you would do: [ 0.25 \times 200 = 50 ]
Examples
Here are a few examples to illustrate the process:
-
Example 1: What is 30% of 150?
- Convert 30% into decimal: 0.30
- Multiply: (0.30 \times 150 = 45)
- Answer: 30% of 150 is 45.
-
Example 2: What is 10% of 80?
- Convert 10% into decimal: 0.10
- Multiply: (0.10 \times 80 = 8)
- Answer: 10% of 80 is 8.
