1. Introduction to Percentages
What is a Percentage?
A percentage is a way of expressing a number as a fraction of 100. It’s denoted by the symbol “%.” In essence, a percentage represents a part out of a whole. For example, 50% means half, or 50 out of 100, while 25% means a quarter, or 25 out of 100. Percentages are essential for simplifying comparisons between different quantities, especially when those quantities are part of a larger whole.
Understanding how to calculate percentages allows us to better grasp ratios, proportions, and many practical applications like calculating discounts, interest rates, and growth rates.
Importance of Percentage Calculations
Percentage calculations are ubiquitous in daily life. Whether you’re calculating your tax rate, interest on a loan, or a sale discount, you rely on percentages. They help us make sense of relative comparisons, which is crucial in personal finance, business, education, and even sports.

The core problem we are addressing is how to determine what percent 403.71 is of 587.50. This type of problem falls into the category of percentage problems where we are finding the percentage part of a whole.
Here’s the general formula for finding a percentage:Percentage=(PartWhole)×100\text{Percentage} = \left(\frac{\text{Part}}{\text{Whole}}\right) \times 100Percentage=(WholePart)×100
In this case:
- Part = 403.71
- Whole = 587.50
By plugging these values into the formula, we get:Percentage=(403.71587.50)×100=68.7165957%\text{Percentage} = \left(\frac{403.71}{587.50}\right) \times 100 = 68.7165957\%Percentage=(587.50403.71)×100=68.7165957%
Thus, 403.71 is approximately 68.72% of 587.50.
3. Step-by-Step Process to Solve the Problem
Step 1: Understand the Formula
To solve any percentage problem like “403.71 is what percent of 587.50?”, we need to use the following percentage formula:Percentage=(PartWhole)×100\text{Percentage} = \left(\frac{\text{Part}}{\text{Whole}}\right) \times 100Percentage=(WholePart)×100
This formula helps us find the percentage when we know the part (403.71) and the whole (587.50).
