Simplifying 15/27 To Lowest Terms

Quick Links :

Simplifying fractions is an essential skill in mathematics, and it's a great way to ensure that your answers are in the most straightforward form possible. In this article, we'll explore the process of simplifying the fraction 15/27 to its lowest terms.

Understanding Fractions

Before we dive into simplifying fractions, let's take a quick look at what fractions are and how they work. A fraction is a way of expressing a part of a whole as a ratio of two numbers. The top number, called the numerator, tells us how many equal parts we have, while the bottom number, called the denominator, tells us how many parts the whole is divided into.

For example, the fraction 3/4 tells us that we have 3 equal parts out of a total of 4 parts. To simplify a fraction, we need to find the greatest common divisor (GCD) of the numerator and the denominator.

What is the Greatest Common Divisor (GCD)?

The greatest common divisor (GCD) is the largest number that divides both the numerator and the denominator without leaving a remainder. To find the GCD, we can use a variety of methods, including prime factorization, the Euclidean algorithm, or simply listing the factors of each number.

For the fraction 15/27, we need to find the GCD of 15 and 27. Let's take a look at the factors of each number:

• Factors of 15: 1, 3, 5, 15
• Factors of 27: 1, 3, 9, 27

As we can see, the greatest common divisor of 15 and 27 is 3.

Simplifying the Fraction

Now that we have the GCD, we can simplify the fraction by dividing both the numerator and the denominator by the GCD. In this case, we'll divide both 15 and 27 by 3:

• 15 ÷ 3 = 5
• 27 ÷ 3 = 9

So, the simplified fraction is 5/9.
