Calculating percentages might seem complex, but don't worry! It's a useful skill applicable in daily life, from figuring out discounts to interpreting test scores. In this friendly guide, we'll break down the steps to help you easily calculate percentages with confidence.

1. Understanding Percentages:

- A percentage expresses a part of a whole as a fraction of 100. For instance, 20% means 20 out of every 100.

2. The Basic Formula:

- The basic formula for calculating a percentage is:

- Percentage = (Part / Whole) * 100

- Here, "Part" is the portion you want a percentage of, and "Whole" is the total.

3. Step-by-Step Calculation:

- Step 1: Identify the Part and the Whole:

- Identify the specific part and the total amount (whole).

- Step 2: Plug the Values into the Formula:

- Substitute the values into the formula: Percentage = (Part / Whole) * 100

- Step 3: Calculate:

- Perform the calculations to find the percentage.

4. Examples:

- Example 1: Finding 15% of 80:

- Part = 15, Whole = 80

- Percentage = (15 / 80) * 100

- Percentage = 18.75%

- Example 2: Calculating a 25% Discount on a $40 Item:

- Part = Discount (25% of $40)

- Whole = Original Price ($40)

- Percentage = (Discount / Original Price) * 100

- Percentage = (0.25 40 / 40) 100 = 25%

5. Tips:

- If you need to find the whole when you know the part and the percentage, rearrange the formula: Whole = (Part / Percentage) * 100.

- Remember, percentages can be written as decimals or fractions. For example, 25% can be 0.25 or 1/4.

- Practice makes perfect! Try calculating percentages in various situations to reinforce your understanding.

Final word

Calculating percentages might seem challenging initially, but with a bit of practice, it becomes second nature. Whether you're determining a discount, analyzing data, or working on a math problem, the ability to calculate percentages is a valuable skill that empowers you to understand and interpret information. Happy calculating!
