Simplify the Fraction: $\frac{5}{20} = $

Simplifying fractions is an essential skill in mathematics, and it's a fundamental concept that students learn in elementary school. In this article, we will focus on simplifying the fraction $\frac{5}{20}$ , which is a common example used in mathematics education. We will explore the steps involved in simplifying this fraction and provide a clear explanation of the process.

What is a Simplified Fraction?

A simplified fraction is a fraction that has been reduced to its lowest terms, meaning that the numerator and denominator have no common factors other than 1. In other words, a simplified fraction is a fraction that cannot be reduced further. For example, the fraction $\frac{2}{4}$ can be simplified to $\frac{1}{2}$ , because 2 and 4 have a common factor of 2.

Step 1: Find the Greatest Common Divisor (GCD)

To simplify the fraction $\frac{5}{20}$ , we need to find the greatest common divisor (GCD) of the numerator and denominator. The GCD is the largest number that divides both numbers without leaving a remainder. In this case, the GCD of 5 and 20 is 5.

Step 2: Divide the Numerator and Denominator by the GCD

Once we have found the GCD, we can divide both the numerator and denominator by the GCD to simplify the fraction. In this case, we can divide 5 by 5 to get 1, and we can divide 20 by 5 to get 4.

Simplifying the Fraction

Now that we have divided the numerator and denominator by the GCD, we can simplify the fraction. The simplified fraction is $\frac{1}{4}$ .
