Understanding fractions
A. Definition of a fraction
Fractions are a fundamental concept in mathematics that represents a part-to-whole relationship. A fraction consists of two numbers, a numerator and a denominator, separated by a horizontal line. The numerator represents the number of equal parts being considered, while the denominator represents the total number of equal parts that make up the whole. For example, in the fraction 1/3, the numerator is 1 and the denominator is 3.
B. Explanation of numerator and denominator
The numerator and denominator play distinct roles in a fraction. The numerator indicates the quantity or number of parts being considered, while the denominator shows how many equal parts make up the whole. In the fraction 2/3, the numerator is 2, indicating there are two parts being considered. The denominator is 3, indicating that the whole is divided into three equal parts.
Understanding the relationship between the numerator and denominator is crucial for working with fractions effectively. Changing the numerator without altering the denominator can modify the quantity being considered. On the other hand, changing the denominator while keeping the numerator constant alters the size of the parts being considered.
In the case of 1/3 and 2/3, the numerator is the same (1) while the denominator differs (3 and 2, respectively). This difference in denominators highlights the need to explore the relationship between these two fractions.
By delving deeper into fractions and their components, we can develop a solid foundation for grasping the mathematical relationship between 1/3 and 2/3. It is this understanding that will enable us to explore equivalent fractions, simplifying fractions, and various real-life applications that involve these fractions.

Simplifying fractions not only makes them easier to work with, but it also helps us compare fractions and find equivalent fractions more easily.
Steps to simplify fractions using prime factors
To simplify a fraction, we can use prime factors. Prime factors are the prime numbers that can divide a given number evenly. The steps to simplify fractions using prime factors are as follows:
1. Find the prime factors of both the numerator and the denominator. Start by dividing the number by the smallest prime number (2) and continue dividing until the number can no longer be divided evenly.
2. Identify the common prime factors (if any) between the numerator and the denominator.
3. Divide both the numerator and the denominator by the common prime factors to reduce the fraction to its simplest form.
For example, let’s simplify the fraction 8/12 using prime factors. The prime factors of 8 are 2 x 2 x 2, and the prime factors of 12 are 2 x 2 x 3. The common prime factors between 8 and 12 are 2 x 2. By dividing both the numerator and the denominator by 2 x 2, the fraction simplifies to 4/6. Continuing the process, we find that 4/6 can be simplified further to 2/3.
By following these steps, we can simplify fractions and determine their relationship more easily. In the case of the relationship between 1/3 and 2/3, simplifying the fractions reveals that they are not equal. While they have a common factor of 1/3, the fractions have different denominators. Through simplification, we can determine that 2/3 is two times as large as 1/3, highlighting the mathematical relationship between them.

VIAddition and Subtraction with Fractions
A. Explanation of adding and subtracting fractions
Adding and subtracting fractions involves combining or separating parts of a whole. When adding or subtracting fractions, it is important to have a common denominator.
To add fractions, the denominators must be the same. If they are not, the fractions need to be converted into equivalent fractions with the same denominator. Once the denominators are the same, the numerators are added together and the sum is placed over the common denominator.
For example, if we want to add 1/3 and 2/3, their denominators are already the same, so we simply add the numerators: 1 + 2 = 3. Therefore, 1/3 + 2/3 = 3/3. Since the numerator and denominator are the same, the sum simplifies to 1.
Subtracting fractions is a similar process. Again, the denominators must be the same. If they are not, the fractions need to be converted into equivalent fractions with the same denominator. Once the denominators are the same, the numerators are subtracted and the result is placed over the common denominator.
For example, if we want to subtract 2/3 from 1/3, their denominators are already the same. We subtract the numerators: 1 – 2 = -1. Therefore, 1/3 – 2/3 = -1/3.
