Introduction

When it comes to multiplying and simplifying fractions, it's essential to understand the concept of lowest terms. In this article, we will delve into the world of fraction multiplication and simplification, focusing on the process of multiplying fractions and simplifying them to their lowest terms. We will explore the steps involved in multiplying fractions, the importance of simplifying fractions, and provide a step-by-step guide on how to simplify fractions to their lowest terms.

What are Fractions?

Before we dive into the world of fraction multiplication and simplification, 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 3/4 can be read as "three-fourths" or "three out of four."

Multiplying Fractions

Multiplying fractions is a straightforward process that involves multiplying the numerators together and the denominators together. The resulting fraction can be simplified to its lowest terms by dividing both the numerator and the denominator by their greatest common divisor (GCD).

Step 1: Multiply the Numerators

To multiply fractions, we start by multiplying the numerators together. In the case of the fractions 6/7 and 2/5, we multiply 6 and 2 to get 12.

Step 2: Multiply the Denominators

Next, we multiply the denominators together. In this case, we multiply 7 and 5 to get 35.

Step 3: Simplify the Resulting Fraction

Now that we have multiplied the numerators and denominators, we can simplify the resulting fraction by dividing both the numerator and the denominator by their GCD. In this case, the GCD of 12 and 35 is 1, so the fraction 12/35 is already in its lowest terms.

Why Simplify Fractions?

Simplifying fractions is an essential step in mathematics, as it helps to:

Reduce the complexity of fractions
Make calculations easier
Avoid errors
Improve understanding of mathematical concepts

How to Simplify Fractions to Lowest Terms

Simplifying fractions to their lowest terms involves dividing both the numerator and the denominator by their GCD. Here's a step-by-step guide on how to simplify fractions:

Step 1: Find the Greatest Common Divisor (GCD)

To simplify a fraction, we need to find the 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.

Step 2: Divide the Numerator and Denominator by the GCD

Once we have found the GCD, we can divide both the numerator and the denominator by the GCD to simplify the fraction.

Step 3: Write the Simplified Fraction

After dividing the numerator and denominator by the GCD, we can write the simplified fraction.

Example: Simplifying the Fraction 12/35

Let's use the fraction 12/35 as an example to illustrate the process of simplifying fractions.

Step 1: Find the GCD

To simplify the fraction 12/35, we need to find the GCD of 12 and 35. The GCD of 12 and 35 is 1.

Step 2: Divide the Numerator and Denominator by the GCD

Since the GCD is 1, we can divide both the numerator and the denominator by 1 to simplify the fraction. This results in the fraction 12/35.

Step 3: Write the Simplified Fraction

The simplified fraction is 12/35.
