Before diving into how our calculator works, let's quickly review the core concepts of percentage calculations. The term "percentage" comes from the Latin "per centum," meaning "by the hundred." Essentially, a percentage is a fraction or ratio where the value of the whole is always considered to be 100.
There are three primary types of percentage problems you'll likely encounter:
- Finding a Percentage of a Number: This involves determining a specific portion of a given value. For example, calculating 15% of 200.
- Determining What Percentage One Number is of Another: This calculates the proportion of one number in relation to another. For instance, figuring out what percentage 30 is of 150.
- Calculating Percentage Increase or Decrease: This calculates the relative change between two values, expressing the change as a percentage. An example would be calculating the percentage change from 80 to 100.

Beyond the Basics: Exploring Percentage Calculations
Understanding percentages also involves knowing how to convert them to decimals and fractions, and vice versa. These skills are useful in many mathematical and practical contexts.
- Converting Percentage to Decimal: Divide the percentage by 100. For example, 75% becomes 0.75.
- Converting Decimal to Percentage: Multiply the decimal by 100. For example, 0.6 becomes 60%.
- Converting Percentage to Fraction: Write the percentage as a fraction with 100 as the denominator, and simplify if possible. For example, 50% becomes 50/100, which simplifies to 1/2.
