Understanding the Concept of Lowest Terms
In mathematics, reducing a fraction to its lowest terms means expressing it in the simplest form possible. This involves dividing both the numerator and the denominator by their greatest common divisor (GCD). The GCD is the largest number that divides both the numerator and the denominator without leaving a remainder.
The Problem: Reducing the Fraction
The given fraction is . To reduce this fraction to its lowest terms, we need to find the GCD of the numerator and the denominator.
Step 1: Find the Greatest Common Divisor (GCD)
To find the GCD of 6x and 12x, we can list the factors of each number.
- Factors of 6x: 1, 2, 3, 6, x, 2x, 3x, 6x
- Factors of 12x: 1, 2, 3, 4, 6, 12, x, 2x, 3x, 4x, 6x, 12x
The greatest common divisor of 6x and 12x is 6x.
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 6x.
The Final Answer
Therefore, the fraction reduced to its lowest terms is .

Reducing Fractions to Lowest Terms: Q&A =============================================
Frequently Asked Questions
In this article, we'll answer some of the most frequently asked questions about reducing fractions to lowest terms.
Q: What is the greatest common divisor (GCD)?
A: The greatest common divisor (GCD) is the largest number that divides both the numerator and the denominator of a fraction without leaving a remainder.
Q: How do I find the GCD of two numbers?
A: To find the GCD of two numbers, you can list the factors of each number and find the largest number that appears in both lists.
Q: What is the difference between reducing a fraction to its lowest terms and simplifying a fraction?
A: Reducing a fraction to its lowest terms involves dividing both the numerator and the denominator by their GCD, while simplifying a fraction involves canceling out any common factors between the numerator and the denominator.
Q: Can I reduce a fraction to its lowest terms if the numerator and denominator have no common factors?
A: Yes, you can still reduce a fraction to its lowest terms even if the numerator and denominator have no common factors. In this case, the fraction is already in its lowest terms.
Q: How do I know if a fraction is already in its lowest terms?
A: To determine if a fraction is already in its lowest terms, you can try dividing both the numerator and the denominator by their GCD. If the result is the same as the original fraction, then it is already in its lowest terms.
Q: Can I reduce a fraction to its lowest terms if the numerator and denominator have a common factor other than 1?
A: Yes, you can still reduce a fraction to its lowest terms even if the numerator and denominator have a common factor other than 1. In this case, you can divide both the numerator and the denominator by the common factor.
Q: What is the importance of reducing fractions to lowest terms in mathematics?
A: Reducing fractions to lowest terms is an essential skill in mathematics, particularly in algebra and calculus. It helps to simplify complex expressions and make them easier to work with.
Q: Can I use a calculator to reduce a fraction to its lowest terms?
A: Yes, you can use a calculator to reduce a fraction to its lowest terms. However, it's essential to understand the concept of reducing fractions to lowest terms and how to do it manually.
Q: How do I reduce a fraction to its lowest terms with variables?
A: To reduce a fraction to its lowest terms with variables, you can follow the same steps as reducing a fraction to its lowest terms with numbers. However, you need to be careful when dividing variables.
Q: Can I reduce a fraction to its lowest terms if the numerator and denominator have a variable in common?
A: Yes, you can still reduce a fraction to its lowest terms even if the numerator and denominator have a variable in common. In this case, you can divide both the numerator and the denominator by the variable.
