Understanding Simplifying Fractions

Fractions are a fundamental concept in mathematics, and simplifying them is an essential skill that can help you solve problems more efficiently. In this article, we will explore the concept of simplifying fractions, specifically the fraction 18/20, and provide a step-by-step guide on how to simplify it to its simplest form.

What is a Fraction?

A fraction is a way to represent a part of a whole. It consists of two numbers: the numerator (the top number) and the denominator (the bottom number). The numerator tells us how many equal parts we have, and the denominator tells us how many parts the whole is divided into.

Why Simplify Fractions?

Simplifying fractions is important because it helps us to:

• Reduce the complexity of mathematical expressions
• Make calculations easier and more efficient
• Compare fractions more easily
• Solve problems more accurately

How to Simplify a Fraction

To simplify a fraction, we need to find the greatest common divisor (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.

Here are the steps to simplify a fraction:

1. Find the factors of the numerator and the denominator.
2. Identify the common factors.
3. Divide the numerator and the denominator by the greatest common factor.

Simplifying 18/20

To simplify the fraction 18/20, we need to find the GCD of 18 and 20.

The factors of 18 are: 1, 2, 3, 6, 9, and 18. The factors of 20 are: 1, 2, 4, 5, 10, and 20.

The common factors of 18 and 20 are: 1 and 2.

The greatest common factor of 18 and 20 is 2.

Now, we can simplify the fraction by dividing the numerator and the denominator by 2:

18 ÷ 2 = 9 20 ÷ 2 = 10

So, the simplified form of 18/20 is 9/10.

Examples of Simplified Fractions
