Understanding Percentages

Percentages are a way to express a value as a fraction of 100. In other words, a percentage is a number that represents a proportion of a whole. For example, 10% means 10 out of 100, or 1 out of 10. Percentages are commonly used in finance, business, and everyday life to express rates of change, growth, or comparison.

Calculating Percentages: A Simple Formula

To calculate a percentage, you can use the following formula:

Percentage = (Part/Whole) x 100

Where:

  • Part is the value you want to find the percentage for
  • Whole is the total value or 100

For example, if you want to find 10% of 12, you can plug in the values as follows:

Percentage = (12/100) x 100

Simplifying the Calculation

To simplify the calculation, you can cancel out the 100 in the numerator and denominator:

Percentage = 12/1 x 100

Performing the Calculation

Now, you can perform the calculation:

Percentage = 12 x 100

Percentage = 1200

Conclusion

Calculating percentages is a simple process that involves using a formula and performing a basic calculation. By understanding percentages and how to calculate them, you can make informed decisions in finance, business, and everyday life.
