Introduction

Mathematics is a fundamental subject that plays a crucial role in our daily lives. It is used to solve problems, make calculations, and understand various concepts. In this article, we will focus on a simple yet interesting math problem that involves fractions and basic arithmetic operations. The problem states that there are 24 children in a class, and a certain fraction of them go out for intervention and music lessons. We will use this problem to demonstrate how to calculate the number of children left in the class.

Understanding the Problem

Let's break down the problem and understand what is being asked. We have 24 children in a class, and we need to find out how many are left after some of them go out for intervention and music lessons. The fractions given are ⅜ (three-eighths) for intervention and ⅙ (one-sixth) for music lessons. We need to calculate the number of children that go out for each activity and then subtract that from the total number of children to find the number left in the class.

Calculating the Number of Children for Intervention

To calculate the number of children that go out for intervention, we need to multiply the total number of children (24) by the fraction ⅜ (three-eighths). We can convert the fraction to a decimal by dividing the numerator (3) by the denominator (8), which gives us 0.375. Now, we can multiply 24 by 0.375 to get the number of children that go out for intervention.

# Calculating the number of children for intervention
total_children = 24
fraction_intervention = 3/8
children_intervention = total_children * fraction_intervention
print("Number of children for intervention:", children_intervention)

Calculating the Number of Children for Music Lessons

Similarly, we need to calculate the number of children that go out for music lessons. We can multiply the total number of children (24) by the fraction ⅙ (one-sixth). We can convert the fraction to a decimal by dividing the numerator (1) by the denominator (6), which gives us 0.1667. Now, we can multiply 24 by 0.1667 to get the number of children that go out for music lessons.

# Calculating the number of children for music lessons
fraction_music = 1/6
children_music = total_children * fraction_music
print("Number of children for music lessons:", children_music)

Calculating the Number of Children Left in the Class

Now that we have calculated the number of children that go out for intervention and music lessons, we can subtract these numbers from the total number of children to find the number left in the class. We can use the following formula:

Number of children left = Total number of children - (Number of children for intervention + Number of children for music lessons)

# Calculating the number of children left in the class
children_left = total_children - (children_intervention + children_music)
print("Number of children left in the class:", children_left)

Conclusion

In this article, we used a simple math problem to demonstrate how to calculate the number of children left in a class after some of them go out for intervention and music lessons. We used fractions and basic arithmetic operations to solve the problem. The problem required us to calculate the number of children that go out for each activity and then subtract that from the total number of children to find the number left in the class. We used Python code to calculate the numbers and provide a clear and concise solution to the problem.

Final Answer

The final answer to the problem is the number of children left in the class, which is calculated using the formula:

Number of children left = Total number of children - (Number of children for intervention + Number of children for music lessons)

We can use the Python code provided to calculate the number of children left in the class.

Additional Tips and Resources

To solve this problem, you need to have a basic understanding of fractions and arithmetic operations.
You can use a calculator or a computer program to calculate the numbers.
This problem is a great example of how math is used in real-life situations.
You can try to modify the problem by changing the fractions or the total number of children to make it more challenging.

Frequently Asked Questions (FAQs) About Fractions

Q: What is a fraction?

A: A fraction is a way of expressing a part of a whole. It consists of a numerator (the top number) and a denominator (the bottom number).

Q: How do I add fractions?

A: To add fractions, you need to have the same denominator. If the denominators are different, you need to find the least common multiple (LCM) of the denominators and then convert the fractions to have the LCM as the denominator.

Q: How do I subtract fractions?

A: To subtract fractions, you need to have the same denominator. If the denominators are different, you need to find the least common multiple (LCM) of the denominators and then convert the fractions to have the LCM as the denominator.

Q: How do I multiply fractions?

A: To multiply fractions, you need to multiply the numerators and multiply the denominators.

Q: How do I divide fractions?

A: To divide fractions, you need to invert the second fraction (i.e., flip the numerator and denominator) and then multiply the fractions.
