Calculate The Following:$\[ 3 \frac{4}{9} \times 4 \frac{1}{3} = \\]Submit Your Answer.

Introduction

When it comes to multiplying mixed numbers, it's essential to understand the concept of fractions and how to convert them into improper fractions. In this article, we'll delve into the world of mixed numbers and explore the step-by-step process of multiplying fractions and whole numbers. We'll use the given problem, $3 \frac{4}{9} \times 4 \frac{1}{3}$, as a case study to demonstrate the process.

Understanding Mixed Numbers

A mixed number is a combination of a whole number and a fraction. It's denoted by a whole number followed by a fraction, such as $3 \frac{4}{9}$. To work with mixed numbers, it's crucial to understand the concept of equivalent fractions. An equivalent fraction is a fraction that has the same value as the original fraction but with different numerators and denominators.

Converting Mixed Numbers to Improper Fractions

To multiply mixed numbers, it's often easier to convert them into improper fractions. An improper fraction is a fraction where the numerator is greater than or equal to the denominator. To convert a mixed number to an improper fraction, we multiply the whole number by the denominator and add the numerator.

For example, let's convert the mixed number $3 \frac{4}{9}$ to an improper fraction:

$3 \frac{4}{9} = \frac{(3 \times 9) + 4}{9} = \frac{27 + 4}{9} = \frac{31}{9}$

Similarly, let's convert the mixed number $4 \frac{1}{3}$ to an improper fraction:

$4 \frac{1}{3} = \frac{(4 \times 3) + 1}{3} = \frac{12 + 1}{3} = \frac{13}{3}$

Multiplying Fractions and Whole Numbers

Now that we have the mixed numbers converted to improper fractions, we can multiply them together. When multiplying fractions, we multiply the numerators together and the denominators together.

Let's multiply the two improper fractions:

$\frac{31}{9} \times \frac{13}{3} = \frac{(31 \times 13)}{(9 \times 3)} = \frac{403}{27}$

Simplifying the Result

The resulting fraction, $\frac{403}{27}$, can be simplified by dividing both the numerator and the denominator by their greatest common divisor (GCD). The GCD of 403 and 27 is 1, so the fraction cannot be simplified further.

Conclusion

In conclusion, multiplying mixed numbers requires converting them into improper fractions and then multiplying the fractions together. By following the step-by-step process outlined in this article, you can master the art of multiplying fractions and whole numbers. Remember to convert mixed numbers to improper fractions, multiply the fractions together, and simplify the resulting fraction if possible.

Final Answer

The final answer to the problem $3 \frac{4}{9} \times 4 \frac{1}{3}$ is $\frac{403}{27}$.

Introduction

In our previous article, we explored the concept of mixed numbers and how to multiply them using improper fractions. However, we know that practice makes perfect, and there's no better way to learn than by asking questions and getting answers. In this article, we'll address some of the most frequently asked questions about multiplying mixed numbers and provide step-by-step solutions.

Q&A

Q: What is the difference between a mixed number and an improper fraction?

A: A mixed number is a combination of a whole number and a fraction, while an improper fraction is a fraction where the numerator is greater than or equal to the denominator.

Q: How do I convert a mixed number to an improper fraction?

A: To convert a mixed number to an improper fraction, multiply the whole number by the denominator and add the numerator. For example, $3 \frac{4}{9} = \frac{(3 \times 9) + 4}{9} = \frac{27 + 4}{9} = \frac{31}{9}$.

Q: What is the greatest common divisor (GCD) and how do I use it to simplify a fraction?

A: The GCD is the largest number that divides both the numerator and the denominator of a fraction. To simplify a fraction, divide both the numerator and the denominator by their GCD. For example, $\frac{403}{27}$ cannot be simplified further because the GCD of 403 and 27 is 1.

Q: Can I multiply mixed numbers without converting them to improper fractions?

A: While it's possible to multiply mixed numbers without converting them to improper fractions, it's often easier and more efficient to convert them first. This is because multiplying mixed numbers can be confusing and prone to errors.

Q: What is the order of operations when multiplying fractions and whole numbers?

A: When multiplying fractions and whole numbers, follow the order of operations:

1. Convert mixed numbers to improper fractions.
2. Multiply the numerators together.
3. Multiply the denominators together.
4. Simplify the resulting fraction if possible.

Q: Can I use a calculator to multiply fractions and whole numbers?

A: While calculators can be helpful, it's essential to understand the concept of multiplying fractions and whole numbers. This will help you to avoid common mistakes and ensure that you're using the calculator correctly.

Q: What are some common mistakes to avoid when multiplying fractions and whole numbers?

A: Some common mistakes to avoid include:

• Failing to convert mixed numbers to improper fractions before multiplying.
• Multiplying the whole numbers together instead of converting them to improper fractions.
• Not simplifying the resulting fraction if possible.

Q: Where can I find more practice problems and resources to help me master multiplying fractions and whole numbers?

A: There are many online resources available to help you practice multiplying fractions and whole numbers, including:

• Khan Academy: www.khanacademy.org
• Mathway: www.mathway.com
• IXL: www.ixl.com
