Mixed Numbers with Like Denominators Made Easy

When it comes to working with fractions, one of the most fundamental concepts is adding mixed numbers with like denominators. While it may seem daunting at first, with a clear understanding of the steps involved, you’ll be able to tackle these types of problems with ease. In this article, we’ll break down the process of adding mixed numbers with like denominators, provide examples, and offer tips to help you master this skill.

What are Mixed Numbers and Like Denominators?

Before we dive into the process of adding mixed numbers with like denominators, let’s quickly review what each of these terms means.

• Mixed Numbers: A mixed number is a combination of a whole number and a fraction. For example, 2 ¹⁄₃ is a mixed number because it consists of a whole number (2) and a fraction (¹⁄₃).
• Like Denominators: Like denominators refer to fractions that have the same denominator. For example, ¹⁄₄ and ³⁄₄ have like denominators because they both have a denominator of 4.

Step-by-Step Guide to Adding Mixed Numbers with Like Denominators

Now that we’ve reviewed the basics, let’s move on to the step-by-step process of adding mixed numbers with like denominators.

1. Identify the Whole Number Parts: Start by identifying the whole number parts of each mixed number. In the example below, the whole number parts are 2 and 1.

Example: 2 ¹⁄₄ + 1 ³⁄₄

1. Add the Whole Number Parts: Add the whole number parts together.

2 + 1 = 3

1. Identify the Fraction Parts: Identify the fraction parts of each mixed number. In the example below, the fraction parts are ¹⁄₄ and ³⁄₄.

2. Add the Fraction Parts: Add the fraction parts together. Since the denominators are the same (4), you can simply add the numerators.

¹⁄₄ + ³⁄₄ = ⁴⁄₄

1. Simplify the Fraction (If Necessary): If the resulting fraction is not in its simplest form, simplify it.

⁴⁄₄ = 1

1. Combine the Whole Number and Fraction Parts: Combine the whole number part (3) with the simplified fraction part (1).

3 + 1 = 4

So, the final answer is 4.

Example Problems

Let’s try a few more example problems to reinforce our understanding of adding mixed numbers with like denominators.

Example 1: 3 ¹⁄₆ + 2 ⁵⁄₆

1. Identify the whole number parts: 3 and 2
2. Add the whole number parts: 3 + 2 = 5
3. Identify the fraction parts: ¹⁄₆ and ⁵⁄₆
4. Add the fraction parts: ¹⁄₆ + ⁵⁄₆ = ⁶⁄₆
5. Simplify the fraction: ⁶⁄₆ = 1
6. Combine the whole number and fraction parts: 5 + 1 = 6

So, the final answer is 6.

Example 2: 1 ³⁄₈ + 2 ⁵⁄₈

1. Identify the whole number parts: 1 and 2
2. Add the whole number parts: 1 + 2 = 3
3. Identify the fraction parts: ³⁄₈ and ⁵⁄₈
4. Add the fraction parts: ³⁄₈ + ⁵⁄₈ = ⁸⁄₈
5. Simplify the fraction: ⁸⁄₈ = 1
6. Combine the whole number and fraction parts: 3 + 1 = 4

So, the final answer is 4.
