Simplifying fractions involves rewriting fractions in their smallest possible form by reducing the numerator and denominator. Being able to reduce fractions to lowest terms is an important foundational math skill.

Simpler fractions are easier to work with in calculations and problem solving. In this post, we’ll simplify the fraction 27/45 step-by-step to its lowest term form. We’ll also explore different methods for reducing fractions and discuss concepts such as greatest common factors that allow us to simplify efficiently.

Here’s a table showing the simplification of the fraction 27/45 to its simplest form:

Fraction | Simplification |
---|---|

27/45 | 3/5 |

The fraction 27/45 simplifies to 3/5 by dividing both the numerator and denominator by their greatest common factor, which is 9.

## What is 27/45 in Simplest Form?

To simplify the fraction 27/45, you can divide both the numerator and denominator by their greatest common factor, which is 9.

27 ÷ 9 = 3 45 ÷ 9 = 5

So, 27/45 simplifies to 3/5 in its simplest form.

## Understanding Fractions

Let’s begin with a quick refresher on fractions. A fraction expresses a numerical amount in parts, with the numerator representing the number of parts and the denominator representing the total number of parts. For example:

In 3/5, the numerator 3 represents 3 parts The denominator 5 represents 5 total parts.

To simplify a fraction, we want to divide both parts by common factors until the fraction is reduced to lowest terms. Let’s look at how to do this for 27/45.

## Simplifying 27/45

When presented with a fraction to reduce:

- Identify the greatest common factor (GCF) between the numerator and denominator.
- Divide both the numerator and denominator by the GCF.

For 27/45:

The GCF of 27 and 45 is 9. Dividing the numerator and denominator by 9 gives us:

27/45 = 3/5

So the fraction 27/45 simplified to lowest terms is 3/5.

## Alternative Methods

Here are some other approaches to reducing 27/45:

- Break the numerator and denominator into prime factors and cancel out common primes. 27 = 3^3, 45 = 3^2*5. Canceling 3^2 gives 3/5.
- Continually divide out common factors. 27/45 -> 9/15 -> 3/5.
- Use a calculator or computer program to simplify. They employ algorithms to efficiently reduce fractions.

The key is finding which factors will cancel out of the top and bottom to produce the lowest fraction possible.

## Proper Simplification

To simplify fractions properly:

- Fully reduce to lowest terms – simplify until no more common factors can divide out.
- Express in positive form – proper fractions have positive numerators and denominators.
- Write numerator/denominator as integers if possible – e.g. 4/3 -> 1 1/3.
- Keep only one fraction if simplifying a sum – 1/2 + 3/6 = 2/3.

Mastering these rules develops fluency in fraction manipulation.
