Introduction

Fractions are a fundamental concept in mathematics, and simplifying them is an essential skill to master. In this article, we will focus on simplifying the fraction $\frac{9}{54}$ to its simplest form. We will explore the concept of greatest common divisors (GCDs), prime factorization, and the steps involved in simplifying fractions.

What is a Simplified Fraction?

A simplified fraction is a fraction that cannot be reduced further by dividing both the numerator and the denominator by a common factor. In other words, a simplified fraction is a fraction that has been reduced to its lowest terms. For example, the fraction $\frac{6}{8}$ can be simplified to $\frac{3}{4}$ by dividing both the numerator and the denominator by 2.

Step 1: Find the Greatest Common Divisor (GCD)

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. In the case of the fraction $\frac{9}{54}$ , we need to find the GCD of 9 and 54.

Finding the GCD

To find the GCD of 9 and 54, we can use the following steps:

List the factors of 9: 1, 3, 9
List the factors of 54: 1, 2, 3, 6, 9, 18, 27, 54
Identify the common factors: 1, 3, 9
Choose the largest common factor: 9

Therefore, the GCD of 9 and 54 is 9.

Step 2: Divide the Numerator and the Denominator by the GCD

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

$\frac{9}{54} = \frac{9 \div 9}{54 \div 9} = \frac{1}{6}$

Therefore, the simplified form of the fraction $\frac{9}{54}$ is $\frac{1}{6}$ .

Conclusion

Simplifying fractions is an essential skill in mathematics, and it requires a good understanding of the concept of greatest common divisors (GCDs) and prime factorization. By following the steps outlined in this article, we can simplify fractions to their lowest terms. In this article, we simplified the fraction $\frac{9}{54}$ to its simplest form, which is $\frac{1}{6}$ .
