Calculate Percentages with Ease! →The Basic Concept
Since percentage literally means "per hundred", figuring out a percentage *out of 100* is incredibly straightforward. The number itself is the percentage. For example:
- If you have 25 out of 100, that's 25%.
- If you have 78 out of 100, that's 78%.
- If you have 99 out of 100, that's 99%.
The beauty of percentages is their simplicity when the total is 100. You can immediately grasp the proportion without further calculation.
What if the Total Isn't 100?
While the concept is simple with a total of 100, many situations involve different totals. Here's how to calculate the percentage in those cases:
- Divide: Divide the specific number you're interested in by the total number.
- Multiply: Multiply the result by 100.
Formula: (Specific Number / Total Number) * 100 = Percentage
Examples of Percentage Calculations
Let's solidify the understanding with some practical examples:
- Example 1: In a class of 50 students, 35 are present. What percentage of students are present?
- (35 / 50) * 100 = 70%
- Example 2: A store offers a discount of $20 on an item originally priced at $80. What is the percentage discount?
- (20 / 80) * 100 = 25%
- Example 3: You scored 65 out of 75 on a test. What is your percentage score?
- (65 / 75) * 100 = 86.67% (approximately)
- Example 4: A company's revenue increased from $500,000 to $600,000. What is the percentage increase?
- (($600,000 - $500,000) / $500,000) * 100 = 20%
