What is a Percentage?

A percentage is a dimensionless number that represents a fraction of 100. It is commonly used to express how much one quantity is relative to another quantity. For example, if you say that 50% of a class passed an exam, it means half the students (50 out of 100) successfully completed the test. Understanding percentages is foundational not only in mathematics but also in fields such as finance, marketing, and social sciences.

Why Understand Percentages?

Knowing how to calculate percentages is crucial for various reasons:

• Budgeting: When managing household finance, you might need to calculate what percentage of your budget goes to savings or expenditures.
• Shopping: Discounts are often given in percentages, meaning if an item is 20% off, understanding how to calculate the new price is vital.
• Statistics: Percentages are widely used in data representation, allowing for easier comparison between figures.

How to Calculate Percentages

There are a few straightforward methods to find a percentage. Here’s a detailed step-by-step guide on how to do this:

Method 1: The Basic Formula

The most common formula for calculating a percentage is:

Percentage = (Part / Whole) × 100

Here, « Part » represents the portion of the whole amount (the total we are interested in), and « Whole » is the total amount you are measuring against.

Example:

Suppose you want to find out what percentage 30 is of 200.

1. Identify the part (30) and the whole (200).
2. Use the formula: (30 / 200) × 100 = 15%
3. Thus, 30 is 15% of 200.

Method 2: Finding the Percentage of a Number

Sometimes, you may need to find out a specific percentage of a number.

The formula for this is:

Percentage of a number = (Percentage × Number) / 100

Example:

If you want to find 25% of 80:

1. Use the formula: (25 × 80) / 100 = 20
2. Therefore, 25% of 80 is 20.

Method 3: Increase or Decrease by a Percentage

You might often need to increase or decrease a number by a certain percentage. Here’s how to do it:

New Value = Original Value ± (Percentage × Original Value) / 100

Example:

If you want to increase 50 by 20%:

1. Calculate the increase: (20 × 50) / 100 = 10
2. Add this to the original number: 50 + 10 = 60
3. So, 50 increased by 20% is 60.

Practice Problems

To help reinforce your understanding, here are a few practice problems:

• What is 40% of 250?
• If a shirt costs $40 after a 20% discount, what was its original price?
• A student scored 45 out of 60 on a test. What percentage did they score?
