## 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%.
