## How To Calculate Percentages?

Here’s a straightforward guide on how to calculate percentages with formulas and examples:

### 1. Understanding the Basics:

**What is a Percentage?:**A percentage is a proportion or a fraction of 100. It represents a part of a whole expressed in terms of one hundred.**Percentage Formula:**The basic formula to calculate a percentage is: Percentage = ( Part / Whole ) Ã— 100%

### 2. Steps to Calculate Percentages:

**Identify the Whole:**Determine the total or the whole amount. This represents 100%.**Determine the Part:**Find the portion or the part of the whole that you want to express as a percentage.**Apply the Formula:**Use the formula above to calculate the percentage by dividing the part by the whole and multiplying by 100%.

### 3. Examples:

**Example 1: Calculating a Percentage of a Whole:**

**Problem:**What is 20% of 150?**Solution:****Step 1:**Identify the whole: Whole = 150**Step 2:**Determine the part: 20% of 150**Step 3:**Apply the formula:

Percentage = ( 20 / 150 ) Ã— 100% = ( 20 / 150 ) Ã— 100 = 13.33%**Answer:**20% of 150 is 30.

**Example 2: Finding the Percentage Change:**

**Problem:**If a stock’s value increased from $50 to $60, what is the percentage increase?**Solution:****Step 1:**Identify the initial value (old value) and the final value (new value):

Old value = 50, New value = 60**Step 2:**Determine the change: Change = New value âˆ’ Old value = 60 âˆ’ 50 = 10**Step 3:**Apply the formula:

Percentage change = ( Change / Old value ) Ã— 100% = ( 10 / 50 ) Ã— 100 = 20%**Answer:**The percentage increase is 20%.

### 4. Additional Tips:

**Percentage Increase/Decrease:**When finding the percentage increase, the formula is ( New Value âˆ’ Old Value ) / Old Value Ã— 100. For a percentage decrease, it’s ( Old Value âˆ’ New Value ) / Old Value Ã— 100.**Converting a Percentage to a Decimal:**Divide the percentage by 100 to convert it to a decimal. For example, 20% is 0.20 in decimal form.
