Understanding Fractions
Before diving into the addition of fractions, it’s important to understand what fractions are. A fraction consists of two parts: the numerator and the denominator. The numerator indicates how many parts we have, while the denominator shows how many equal parts the whole is divided into.
Key Terms
1. Numerator: The top number of a fraction.
2. Denominator: The bottom number of a fraction.
3. Like Denominators: Fractions that have the same denominator.
The Process of Adding Fractions with Like Denominators
Adding fractions with like denominators is straightforward. The key is to remember that when the denominators are the same, we only add the numerators. The denominator remains constant.
Steps to Add Fractions with Like Denominators
To add fractions with like denominators, follow these simple steps:
1. Identify the Fractions: Look at the fractions you are adding.
2. Ensure the Denominators are the Same: Check if the denominators are identical. If they are not, you cannot proceed with this method.
3. Add the Numerators: Combine the numerators while keeping the denominator the same.
4. Simplify if Necessary: If the resulting fraction can be simplified, do so.
Example of Adding Fractions with Like Denominators
Let’s take an example to illustrate the process:
- Example: Add \( \frac{3}{5} + \frac{1}{5} \)
1. Check the denominators: Both fractions have a denominator of 5.
2. Add the numerators: \( 3 + 1 = 4 \)
3. Keep the denominator: The sum is \( \frac{4}{5} \).
4. Simplify: \( \frac{4}{5} \) is already in its simplest form.
Practice Problems
To help solidify understanding, students can practice adding fractions with like denominators. Here are some practice problems:
1. \( \frac{2}{7} + \frac{3}{7} \)
2. \( \frac{5}{8} + \frac{1}{8} \)
3. \( \frac{4}{12} + \frac{2}{12} \)
4. \( \frac{6}{10} + \frac{3}{10} \)
5. \( \frac{9}{15} + \frac{4}{15} \)
Answers:
1. \( \frac{5}{7} \)
2. \( \frac{6}{8} = \frac{3}{4} \)
3. \( \frac{6}{12} = \frac{1}{2} \)
4. \( \frac{9}{10} \)
5. \( \frac{13}{15} \)
