Introduction

Simplifying fractions is an essential skill in mathematics, and it's a fundamental concept that students and professionals alike need to master. In this article, we'll delve into the world of fractions and explore the process of simplifying them. We'll start with a simple example and work our way up to more complex ones, providing step-by-step explanations and examples to help you understand the concept.

What are Fractions?

Before we dive into simplifying fractions, let's first understand what fractions are. A fraction is a way of expressing a part of a whole as a ratio of two numbers. It consists of a numerator (the top number) and a denominator (the bottom number). For example, the fraction $\frac{1}{2}$ represents one half of a whole.

Simplifying Fractions: A Step-by-Step Guide

Simplifying fractions involves reducing a fraction to its simplest form, which means expressing it with the smallest possible numerator and denominator. To simplify a fraction, we need to find the greatest common divisor (GCD) of the numerator and denominator.

Finding the Greatest Common Divisor (GCD)

The GCD of two numbers is the largest number that divides both numbers without leaving a remainder. To find the GCD, we can use the following methods:

• Prime Factorization: This method involves breaking down both numbers into their prime factors and then finding the product of the common factors.
• Euclidean Algorithm: This method involves using a series of division steps to find the GCD.

Let's use the prime factorization method to find the GCD of 14 and 28.

Step 1: Break down 14 and 28 into their prime factors.

• 14 = 2 × 7
• 28 = 2 × 2 × 7

Step 2: Identify the common factors.

• The common factors are 2 and 7.

Step 3: Multiply the common factors.

• 2 × 7 = 14

Therefore, the GCD of 14 and 28 is 14.

Simplifying the Fraction

Now that we have found the GCD, we can simplify the fraction.

Step 1: Divide both the numerator and denominator by the GCD.

• $\frac{14}{28} = \frac{14 ÷ 14}{28 ÷ 14} = \frac{1}{2}$

Therefore, the simplified fraction is $\frac{1}{2}$.

Example 2: Simplifying $\frac{18}{36}$

Let's use the same steps to simplify the fraction $\frac{18}{36}$.

Step 1: Find the GCD of 18 and 36.

• 18 = 2 × 3 × 3
• 36 = 2 × 2 × 3 × 3

Step 2: Identify the common factors.

• The common factors are 2 and 3 × 3.

Step 3: Multiply the common factors.

• 2 × 3 × 3 = 18

Therefore, the GCD of 18 and 36 is 18.

Step 4: Divide both the numerator and denominator by the GCD.

• $\frac{18}{36} = \frac{18 ÷ 18}{36 ÷ 18} = \frac{1}{2}$

Therefore, the simplified fraction is $\frac{1}{2}$.

Example 3: Simplifying $\frac{24}{48}$

Let's use the same steps to simplify the fraction $\frac{24}{48}$.

Step 1: Find the GCD of 24 and 48.

• 24 = 2 × 2 × 2 × 3
• 48 = 2 × 2 × 2 × 2 × 3

Step 2: Identify the common factors.

• The common factors are 2 × 2 × 2 and 3.

Step 3: Multiply the common factors.

• 2 × 2 × 2 = 8
• 8 × 3 = 24

Therefore, the GCD of 24 and 48 is 24.

Step 4: Divide both the numerator and denominator by the GCD.

• $\frac{24}{48} = \frac{24 ÷ 24}{48 ÷ 24} = \frac{1}{2}$

Therefore, the simplified fraction is $\frac{1}{2}$.
