Introduction

Fractions are an essential part of mathematics, and simplifying them is a crucial skill to master. In this article, we will explore the concept of simplifying fractions, specifically focusing on the idea that some fractions can be simplified in one step, while others may require several steps. We will delve into the concept of the greatest common factor (GCF) and how it plays a crucial role in simplifying fractions in one step.

What is a Fraction?

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 3/4 represents three parts out of four equal parts. Fractions can be used to represent a wide range of mathematical concepts, from simple ratios to complex algebraic expressions.

Simplifying Fractions

Simplifying fractions involves reducing a fraction to its simplest form, where the numerator and denominator have no common factors other than 1. This is often achieved by dividing both the numerator and denominator by their greatest common factor (GCF). However, as we will discuss later, not all fractions can be simplified in one step.

The Greatest Common Factor (GCF)

The greatest common factor (GCF) of two numbers is the largest number that divides both numbers without leaving a remainder. For example, the GCF of 12 and 18 is 6, because 6 is the largest number that divides both 12 and 18 without leaving a remainder. The GCF plays a crucial role in simplifying fractions, as dividing both the numerator and denominator by their GCF will result in a simplified fraction.

Simplifying Fractions in One Step

If you divide both the numerator and denominator of a fraction by their GCF, you will simplify the fraction in one step. For example, consider the fraction 12/18. The GCF of 12 and 18 is 6, so dividing both numbers by 6 results in the simplified fraction 2/3.

Simplifying Fractions in Several Steps

However, not all fractions can be simplified in one step. If you divide a fraction by a common factor that is not the GCF, you will have to use several steps to simplify the fraction. For example, consider the fraction 12/18. If you divide both numbers by 2, you will get the fraction 6/9. However, 6 and 9 still have a common factor of 3, so you will have to divide both numbers by 3 to get the simplified fraction 2/3.
