$$

Introduction

In this article, we will explore the concept of percentages and how to calculate them. We will use a real-life example to demonstrate how to find the percentage of a given amount. The example we will use is to find the percentage of $N 2.50$ that is 25 kobo.

Understanding Percentages

A percentage is a way to express a value as a fraction of 100. It is calculated by dividing the value by the total and multiplying by 100. For example, if we have a value of $N 2.50$ and we want to find the percentage of it that is 25 kobo, we can use the following formula:

Percentage = (Value / Total) x 100

Calculating the Percentage

To calculate the percentage of $N 2.50$ that is 25 kobo, we need to first convert the kobo to naira. Since there are 100 kobo in 1 naira, we can convert 25 kobo to naira as follows:

25 kobo = 25/100 = 0.25 naira

Now that we have the value in naira, we can use the formula to calculate the percentage:

Percentage = (0.25 / 2.50) x 100

Solving the Equation

To solve the equation, we can start by dividing 0.25 by 2.50:

0.25 / 2.50 = 0.1

Now that we have the result of the division, we can multiply it by 100 to get the percentage:

0.1 x 100 = 10%

Conclusion

Therefore, the percentage of $N 2.50$ that is 25 kobo is 10%. This means that 10% of $N 2.50$ is equal to 25 kobo.
