5 Easy Ways to Add and Subtract Fractions

Learning Fractions Made Easy

Are you struggling to add and subtract fractions? Do you find it challenging to work with different denominators? Don’t worry, we’ve got you covered! In this article, we’ll explore five easy ways to add and subtract fractions. By the end of this post, you’ll be a pro at working with fractions.

Understanding Fractions

Before we dive into the methods, let’s quickly review what fractions are. A fraction is a way to represent a part of a whole. It consists of two numbers: the numerator (the top number) and the denominator (the bottom number). The numerator tells us how many equal parts we have, while the denominator tells us how many parts the whole is divided into.

Method 1: Adding Fractions with the Same Denominator

When adding fractions with the same denominator, we simply add the numerators and keep the denominator the same.

Example: ¹⁄₄ + ¹⁄₄ = ²⁄₄

• We add the numerators (1 + 1) to get 2.
• The denominator remains the same (4).

📝 Note: When adding fractions with the same denominator, make sure to simplify the result, if possible.

Method 2: Adding Fractions with Different Denominators

When adding fractions with different denominators, we need to find the least common multiple (LCM) of the denominators.

Example: ¹⁄₄ + ¹⁄₆ =?

• We find the LCM of 4 and 6, which is 12.
• We convert both fractions to have a denominator of 12:
  • ¹⁄₄ = ³⁄₁₂
  • ¹⁄₆ = ²⁄₁₂
• We add the fractions: ³⁄₁₂ + ²⁄₁₂ = ⁵⁄₁₂

Method 3: Subtracting Fractions with the Same Denominator

When subtracting fractions with the same denominator, we simply subtract the numerators and keep the denominator the same.

Example: ²⁄₄ - ¹⁄₄ = ¹⁄₄

• We subtract the numerators (2 - 1) to get 1.
• The denominator remains the same (4).

Method 4: Subtracting Fractions with Different Denominators

When subtracting fractions with different denominators, we need to find the LCM of the denominators.

Example: ²⁄₄ - ¹⁄₆ =?

• We find the LCM of 4 and 6, which is 12.
• We convert both fractions to have a denominator of 12:
  • ²⁄₄ = ⁶⁄₁₂
  • ¹⁄₆ = ²⁄₁₂
• We subtract the fractions: ⁶⁄₁₂ - ²⁄₁₂ = ⁴⁄₁₂

Method 5: Using Visual Aids

Sometimes, using visual aids can make adding and subtracting fractions easier. We can use circles, rectangles, or other shapes to represent the fractions.

Example: ¹⁄₄ + ¹⁄₄ =?

• We draw two circles to represent the fractions.
• We shade in one-quarter of each circle.
• We combine the shaded parts to get ²⁄₄.

By using these five easy methods, you’ll become more confident in adding and subtracting fractions. Remember to simplify your results and use visual aids when needed.
