The quest for calculating percentages can sometimes seem daunting, but fear not, for the solution is indeed quite straightforward. To find 10% of $25.00, we can follow a simple mathematical approach that requires minimal computation.
Understanding Percentages
First, let’s briefly understand what a percentage represents. The term “percent” means per 100. So, when we talk about 10% of a number, we’re referring to 10 parts out of every 100.
The Calculation
To find 10% of $25.00, we apply the formula for percentages, which is: [ \text{Percentage of a Number} = \left( \frac{\text{Percentage Value}}{100} \right) \times \text{Number} ]
Substituting the given values: [ 10\% \text{ of } 25.00 = \left( \frac{10}{100} \right) \times 25.00 ]
Simplifying the fraction: [ \frac{10}{100} = 0.10 ]
So, the equation becomes: [ 0.10 \times 25.00 ]
The Solution
Now, we simply perform the multiplication: [ 0.10 \times 25.00 = 2.50 ]
Therefore, 10% of 25.00 is 2.50.
Alternative Method
Another quick way to find 10% of a number is to simply move the decimal point one place to the left. For 25.00, moving the decimal point one place to the left gives us 2.50, which is 10% of $25.00.
Conclusion
Calculating percentages is a fundamental mathematical operation that, once understood, can be performed with ease. For finding 10% of any number, the method involves either using the percentage formula or the quicker approach of shifting the decimal point. Both methods yield the same result and demonstrate how straightforward it is to work with percentages in everyday calculations.
