Introduction

When dealing with fractions, simplifying expressions is a crucial step in solving mathematical problems. In this article, we will focus on simplifying the expression $ \frac{1}{3} - \frac{1}{3} $. This may seem like a simple task, but it requires a clear understanding of fractions and their operations. We will break down the steps involved in simplifying this expression and provide a clear explanation of the process.

Understanding Fractions

Fractions are a way of representing part of a whole. They consist of a numerator (the top number) and a denominator (the bottom number). The numerator represents the number of equal parts being considered, while the denominator represents the total number of parts in the whole. For example, the fraction $ \frac{1}{3} $ represents one part out of three equal parts.

Subtracting Fractions

When subtracting fractions, we need to have the same denominator. If the denominators are different, we need to find the least common multiple (LCM) of the two denominators. In this case, we have two fractions with the same denominator, which is 3.

Simplifying the Expression

To simplify the expression $ \frac{1}{3} - \frac{1}{3} $, we need to subtract the two fractions. Since the denominators are the same, we can simply subtract the numerators.

$ \frac{1}{3} - \frac{1}{3} = \frac{1-1}{3} = \frac{0}{3} $

Canceling Out the Zero

When we simplify the expression, we get $ \frac{0}{3} $. This means that the numerator is zero, and the denominator is 3. However, we can simplify this further by canceling out the zero.

$ \frac{0}{3} = 0 $

Conclusion

In conclusion, simplifying the expression $ \frac{1}{3} - \frac{1}{3} $ requires a clear understanding of fractions and their operations. By following the steps outlined in this article, we can simplify the expression and arrive at the final answer of 0.
