Oct 13, 2025 by wbrum.org 3 views

Introduction

Mathematics is a fundamental subject that plays a crucial role in our daily lives. It is used to solve problems, make predictions, and understand the world around us. In this article, we will delve into a simple yet interesting problem that involves basic arithmetic operations. We will calculate the number of children with blue eyes in a group of 32 children, given that 75 percent of them have blue eyes.

Understanding the Problem

To solve this problem, we need to understand the concept of percentages and how to convert them into decimal form. A percentage is a way of expressing a value as a fraction of 100. In this case, 75 percent means that 75 out of every 100 children have blue eyes. To convert this percentage into a decimal, we divide 75 by 100, which gives us 0.75.

Calculating the Number of Children with Blue Eyes

Now that we have the decimal form of the percentage, we can calculate the number of children with blue eyes. We know that 75 percent of the children have blue eyes, and we want to find out how many children that is in a group of 32. To do this, we multiply the total number of children (32) by the decimal form of the percentage (0.75).

# Import necessary modules
import math
total_children = 32
percentage = 0.75
children_with_blue_eyes = total_children * percentage
print("The number of children with blue eyes is:", children_with_blue_eyes)

Solution

When we run the code above, we get the following result:

The number of children with blue eyes is: 24.0

This means that 24 children out of the group of 32 have blue eyes.

Conclusion

In this article, we solved a simple problem involving basic arithmetic operations. We calculated the number of children with blue eyes in a group of 32, given that 75 percent of them have blue eyes. We used the concept of percentages and converted them into decimal form to solve the problem. This problem is a great example of how mathematics is used in real-life scenarios and how it can be applied to solve everyday problems.

Real-World Applications

This problem has several real-world applications. For example, in a school with 32 students, if 75 percent of them have blue eyes, we can use this information to determine the number of students with blue eyes. This can be useful in various situations, such as:

Identifying students with special needs or requirements
Organizing activities or events based on eye color
Conducting surveys or research on eye color distribution

Tips and Variations

Here are some tips and variations to the problem:

What if the group of children has 50 students instead of 32? How many students with blue eyes would there be?
If 25 percent of the children have blue eyes, how many children would that be in a group of 40?
If 50 percent of the children have blue eyes, how many children would that be in a group of 60?

These variations can help you practice and apply the concept of percentages and decimal form to solve different problems.

Final Thoughts

In conclusion, this problem is a great example of how mathematics is used in real-life scenarios. We calculated the number of children with blue eyes in a group of 32, given that 75 percent of them have blue eyes. We used the concept of percentages and converted them into decimal form to solve the problem. This problem has several real-world applications and can be used to practice and apply the concept of percentages and decimal form to solve different problems.

Introduction

In our previous article, we solved a simple problem involving basic arithmetic operations. We calculated the number of children with blue eyes in a group of 32, given that 75 percent of them have blue eyes. In this article, we will provide a Q&A section to help you understand the problem and its solution better.

Q&A

Q1: What is the percentage of children with blue eyes in the group?

A1: The percentage of children with blue eyes in the group is 75 percent.

Q2: How do we convert a percentage into a decimal?

A2: To convert a percentage into a decimal, we divide the percentage by 100. In this case, 75 percent is converted to 0.75 by dividing 75 by 100.

Q3: How do we calculate the number of children with blue eyes?

A3: To calculate the number of children with blue eyes, we multiply the total number of children (32) by the decimal form of the percentage (0.75).

Q4: What is the result of the calculation?

A4: The result of the calculation is 24.0, which means that 24 children out of the group of 32 have blue eyes.

Q5: What if the group of children has 50 students instead of 32? How many students with blue eyes would there be?

A5: To calculate the number of students with blue eyes in a group of 50, we multiply 50 by the decimal form of the percentage (0.75). The result is 37.5, which means that 37.5 students out of the group of 50 have blue eyes.

Q6: If 25 percent of the children have blue eyes, how many children would that be in a group of 40?

A6: To calculate the number of children with blue eyes in a group of 40, we multiply 40 by the decimal form of the percentage (0.25). The result is 10, which means that 10 children out of the group of 40 have blue eyes.

Q7: If 50 percent of the children have blue eyes, how many children would that be in a group of 60?

A7: To calculate the number of children with blue eyes in a group of 60, we multiply 60 by the decimal form of the percentage (0.5). The result is 30, which means that 30 children out of the group of 60 have blue eyes.

Tips and Variations

Here are some tips and variations to the problem:

Practice converting percentages into decimals and vice versa.
Use different percentages and numbers to calculate the number of children with blue eyes.
