Introduction to Multiplying Fractions

Multiplying fractions is a fundamental concept in mathematics that helps us solve various problems in different fields, such as science, engineering, and finance. In this article, we will focus on multiplying two fractions, $\frac{11}{2}$ and $\frac{3}{7}$ , and simplify the result to its simplest form.

Understanding the Concept of Multiplying Fractions

To multiply fractions, we need to understand the concept of multiplying numbers and dividing numbers. When we multiply two numbers, we are essentially adding a number a certain number of times. For example, $3 \times 4$ means adding $3$ together $4$ times, which equals $12$ . On the other hand, when we divide a number by another number, we are essentially finding how many times the divisor fits into the dividend. For instance, $12 \div 3$ means finding how many times $3$ fits into $12$ , which equals $4$ .

Multiplying Fractions: A Step-by-Step Guide

To multiply fractions, we follow a simple step-by-step process:

Multiply the numerators: Multiply the numbers on top of the fractions, which are the numerators. In this case, we multiply $11$ and $3$ .
Multiply the denominators: Multiply the numbers on the bottom of the fractions, which are the denominators. In this case, we multiply $2$ and $7$ .
Write the product of the numerators over the product of the denominators: Write the result of multiplying the numerators over the result of multiplying the denominators.

Applying the Multiplication Rule to the Given Fractions

Now, let's apply the multiplication rule to the given fractions, $\frac{11}{2}$ and $\frac{3}{7}$ .

Step 1: Multiply the Numerators

To multiply the numerators, we simply multiply $11$ and $3$ .

$11 \times 3 = 33$

Step 2: Multiply the Denominators

To multiply the denominators, we simply multiply $2$ and $7$ .

$2 \times 7 = 14$

Step 3: Write the Product of the Numerators over the Product of the Denominators

Now, we write the product of the numerators over the product of the denominators.

$\frac{33}{14}$

Simplifying the Result

To simplify the result, we need to find the greatest common divisor (GCD) of the numerator and the denominator. The GCD is the largest number that divides both the numerator and the denominator without leaving a remainder.

Finding the Greatest Common Divisor (GCD)

To find the GCD of $33$ and $14$ , we can use the Euclidean algorithm or list the factors of each number.

Factors of $33$ : $1, 3, 11, 33$ Factors of $14$ : $1, 2, 7, 14$

The greatest common divisor of $33$ and $14$ is $1$ .

Simplifying the Fraction

Since the GCD of $33$ and $14$ is $1$ , the fraction $\frac{33}{14}$ is already in its simplest form.

Conclusion

In conclusion, multiplying fractions is a straightforward process that involves multiplying the numerators and denominators separately and then writing the product of the numerators over the product of the denominators. To simplify the result, we need to find the greatest common divisor of the numerator and the denominator and divide both numbers by the GCD. In this article, we multiplied the fractions $\frac{11}{2}$ and $\frac{3}{7}$ and simplified the result to its simplest form, which is $\frac{33}{14}$ .
