Percentage Formula:
From: | To: |
Percentage calculation is a mathematical operation that expresses a number as a fraction of 100. It's commonly used to compare proportions and express ratios in a standardized way.
The calculator uses the percentage formula:
Where:
Explanation: The formula converts the fraction of the base into a percentage by multiplying by 100.
Details: Percentage calculations are fundamental in many areas including finance, statistics, science, and everyday life for comparing proportions and changes.
Tips: Enter the fraction as a decimal number and the base as a positive number. The base cannot be zero as division by zero is undefined.
Q1: What if my fraction is greater than the base?
A: The calculator will still work, giving a percentage greater than 100%, which means the fraction exceeds the base value.
Q2: Can I use fractions instead of decimals?
A: Yes, but you'll need to convert the fraction to decimal form first (e.g., 1/4 = 0.25).
Q3: How precise are the results?
A: Results are rounded to 2 decimal places for readability while maintaining reasonable precision.
Q4: What are common applications of this calculation?
A: Common uses include calculating test scores, financial ratios, statistical proportions, and many real-world measurements.
Q5: How is this different from percentage change calculations?
A: This calculates the proportion of one value relative to another, while percentage change calculates the difference between two values relative to the original.
