The Basics of Percentages
Before we dive into the specifics of calculating percentages, it’s important to understand the basics. A percentage is a way to express a portion of a whole as a fraction of 100. For example, 50 percent means 50 out of 100, or half of the whole.
Percentages are used in a variety of contexts, from calculating taxes to determining discounts. Understanding how to calculate percentages is a valuable skill that can come in handy in many areas of life.
Calculating Percentages
Calculating percentages involves a simple formula:
Part/Whole x 100 = Percentage
The “part” refers to the portion of the whole that you want to express as a percentage. The “whole” refers to the total amount. To calculate the percentage, you divide the part by the whole and then multiply by 100.
Calculating 3 is What Percent of 500
Now that we understand the basics of calculating percentages, let’s apply it to the problem at hand: what percentage is 3 of 500?
Using the formula above, we can set up the equation:
3/500 x 100 = ?
To solve for the percentage, we simply divide 3 by 500 and then multiply by 100:
3/500 x 100 = 0.6%
Therefore, 3 is 0.6% of 500.
Why Knowing Percentages is Important
Knowing how to calculate percentages can be useful in many situations. For example, if you’re shopping and see an item that’s on sale for 20% off, you can quickly calculate the sale price to see if it’s a good deal. Or if you’re trying to budget your expenses, you can calculate what percentage of your income is going towards different categories like rent, food, and entertainment.
Percentages are also used in many professions, from finance to healthcare. Understanding percentages can help you analyze data and make informed decisions.
