Understanding Percentages

Percentages are a fundamental concept in mathematics, used to express a fraction of a whole as a number out of 100. The word "percent" comes from the Latin "per centum," meaning "by the hundred." They are widely used in various fields, from finance and statistics to everyday shopping and data analysis.

What is X% of Y?

This calculation helps you find a specific portion of a given number. For example, if you want to know what 20% of 500 is, you're looking for that specific part. The formula is straightforward: (Percentage / 100) * Base Number.

Example: If you get a 15% discount on an item that costs $80, you would calculate 15% of 80 to find the discount amount. Using the calculator, input 15 for 'Percentage (X)' and 80 for 'Base Number (Y)'. The result will be 12, meaning a $12 discount.

Percentage Change from A to B

Percentage change measures the relative difference between an old value and a new value. It's crucial for understanding growth, decline, or fluctuations over time. This can be an increase or a decrease.

The formula for percentage change is: ((New Value - Original Value) / Original Value) * 100.

If the result is positive, it's a percentage increase.
If the result is negative, it's a percentage decrease.

Example: A company's sales increased from 500 units last month to 650 units this month. To find the percentage increase, input 500 for 'Original Value (A)' and 650 for 'New Value (B)'. The calculator will show a 30% increase.

Example (Decrease): The price of a stock dropped from $150 to $120. Input 150 for 'Original Value (A)' and 120 for 'New Value (B)'. The result will be a 20% decrease.

X is what percentage of Y?

This calculation helps you determine what proportion one number represents of another, expressed as a percentage. It's useful for understanding ratios, grades, or market share.

The formula is: (Part / Whole) * 100.

Example: If you scored 45 points out of a possible 60 on a test, you'd want to know what percentage that is. Input 45 for 'Part (X)' and 60 for 'Whole (Y)'. The calculator will show 75%, meaning you scored 75% on the test.

Example: In a class of 30 students, 18 are girls. To find the percentage of girls, input 18 for 'Part (X)' and 30 for 'Whole (Y)'. The result will be 60%, indicating 60% of the class are girls.
