Introduction

Calculating percentage increases is a fundamental concept in mathematics that has numerous real-world applications. Whether you're a student, a business owner, or simply someone who wants to understand how to calculate percentage increases, this article will guide you through the process step by step.

What is a Percentage Increase?

A percentage increase is a way to express a change in value as a percentage of the original value. In other words, it's a way to calculate the amount by which a value has increased or decreased. For example, if you increase £60 by 15%, you want to find out how much the new value will be.

Calculating Percentage Increases

To calculate a percentage increase, you need to follow these steps:

Identify the original value: In this case, the original value is £60.
Identify the percentage increase: The percentage increase is 15%.
Convert the percentage to a decimal: To convert a percentage to a decimal, divide the percentage by 100. In this case, 15% is equal to 0.15.
Multiply the original value by the decimal: Multiply £60 by 0.15 to find the amount by which the value will increase.

Calculating the Increase

£60 x 0.15 = £9

Finding the New Value

To find the new value, add the increase to the original value:

£60 + £9 = £69

Conclusion

In this article, we've learned how to calculate a percentage increase using a simple formula. By following the steps outlined above, you can easily calculate percentage increases and apply them to real-world scenarios. Whether you're a student, a business owner, or simply someone who wants to understand how to calculate percentage increases, this article has provided you with a step-by-step guide to calculating percentage increases.
