Introduction

In mathematics, multiplying mixed numbers is a fundamental operation that requires a clear understanding of fractions and their properties. A mixed number is a combination of a whole number and a fraction, and it is essential to learn how to multiply these numbers to solve various mathematical problems. In this article, we will explore the process of multiplying mixed numbers, using the example of $4 \frac{2}{9} \times 2 \frac{4}{9}$.

Understanding Mixed Numbers

Before we dive into the multiplication process, let's understand what mixed numbers are. A mixed number is a combination of a whole number and a fraction, written in the form $a \frac{b}{c}$. For example, $4 \frac{2}{9}$ is a mixed number where $4$ is the whole number and $\frac{2}{9}$ is the fraction.

Multiplying Mixed Numbers: A Step-by-Step Guide

To multiply mixed numbers, we need to follow a specific process. Here are the steps:

Step 1: Multiply the Whole Numbers

The first step is to multiply the whole numbers. In our example, we have $4 \times 2 = 8$.

Step 2: Multiply the Fractions

Next, we multiply the fractions. To do this, we multiply the numerators (the numbers on top) and the denominators (the numbers on the bottom). In our example, we have $\frac{2}{9} \times \frac{4}{9} = \frac{2 \times 4}{9 \times 9} = \frac{8}{81}$.

Step 3: Add the Whole Number and the Fraction

Now, we need to add the whole number and the fraction. To do this, we need to convert the whole number to a fraction with the same denominator as the fraction we obtained in Step 2. In our example, we have $8 = \frac{8 \times 9}{9} = \frac{72}{9}$. Now, we can add the two fractions: $\frac{72}{9} + \frac{8}{81} = \frac{72 \times 9}{9 \times 9} + \frac{8}{81} = \frac{648}{81} + \frac{8}{81} = \frac{656}{81}$.

Step 4: Simplify the Result

Finally, we need to simplify the result. To do this, we can divide both the numerator and the denominator by their greatest common divisor (GCD). In our example, the GCD of 656 and 81 is 1, so the result is already simplified.

Conclusion

In conclusion, multiplying mixed numbers requires a clear understanding of fractions and their properties. By following the steps outlined above, we can multiply mixed numbers and obtain the correct result. Remember to multiply the whole numbers, multiply the fractions, add the whole number and the fraction, and simplify the result.

Introduction

In our previous article, we explored the process of multiplying mixed numbers. However, we know that practice makes perfect, and there's no better way to practice than by answering questions and solving problems. In this article, we'll provide a Q&A guide to help you understand and practice multiplying mixed numbers.

Q: What is the product of $3 \frac{1}{4} \times 2 \frac{3}{4}$?

A: To solve this problem, we need to multiply the whole numbers first. $3 \times 2 = 6$. Next, we multiply the fractions. $\frac{1}{4} \times \frac{3}{4} = \frac{1 \times 3}{4 \times 4} = \frac{3}{16}$. Now, we add the whole number and the fraction. $6 = \frac{6 \times 16}{16} = \frac{96}{16}$. Finally, we add the two fractions: $\frac{96}{16} + \frac{3}{16} = \frac{99}{16}$.

Q: What is the product of $5 \frac{2}{3} \times 3 \frac{1}{3}$?

A: To solve this problem, we need to multiply the whole numbers first. $5 \times 3 = 15$. Next, we multiply the fractions. $\frac{2}{3} \times \frac{1}{3} = \frac{2 \times 1}{3 \times 3} = \frac{2}{9}$. Now, we add the whole number and the fraction. $15 = \frac{15 \times 9}{9} = \frac{135}{9}$. Finally, we add the two fractions: $\frac{135}{9} + \frac{2}{9} = \frac{137}{9}$.

Q: What is the product of $2 \frac{7}{9} \times 4 \frac{2}{9}$?

A: To solve this problem, we need to multiply the whole numbers first. $2 \times 4 = 8$. Next, we multiply the fractions. $\frac{7}{9} \times \frac{2}{9} = \frac{7 \times 2}{9 \times 9} = \frac{14}{81}$. Now, we add the whole number and the fraction. $8 = \frac{8 \times 81}{81} = \frac{648}{81}$. Finally, we add the two fractions: $\frac{648}{81} + \frac{14}{81} = \frac{662}{81}$.

Q: What is the product of $6 \frac{3}{8} \times 2 \frac{5}{8}$?

A: To solve this problem, we need to multiply the whole numbers first. $6 \times 2 = 12$. Next, we multiply the fractions. $\frac{3}{8} \times \frac{5}{8} = \frac{3 \times 5}{8 \times 8} = \frac{15}{64}$. Now, we add the whole number and the fraction. $12 = \frac{12 \times 64}{64} = \frac{768}{64}$. Finally, we add the two fractions: $\frac{768}{64} + \frac{15}{64} = \frac{783}{64}$.

Q: What is the product of $4 \frac{2}{9} \times 2 \frac{4}{9}$?

A: To solve this problem, we need to multiply the whole numbers first. $4 \times 2 = 8$. Next, we multiply the fractions. $\frac{2}{9} \times \frac{4}{9} = \frac{2 \times 4}{9 \times 9} = \frac{8}{81}$. Now, we add the whole number and the fraction. $8 = \frac{8 \times 9}{9} = \frac{72}{9}$. Finally, we add the two fractions: $\frac{72}{9} + \frac{8}{81} = \frac{656}{81}$.
