➕➖ Adding/Subtracting Like Fractions

📖 What the Section Is About

In this section, students learn how to add and subtract fractions with the same denominator (like fractions). They practice combining or taking away parts of the same whole, and understanding that only the numerator changes while the denominator stays the same.

🎯 Learning Objectives

✅ Add like fractions by adding numerators and keeping the denominator
✅ Subtract like fractions by subtracting numerators and keeping the denominator
✅ Simplify results when possible
✅ Apply addition and subtraction of like fractions in real-life problems

🧮 Examples

Example 1: Adding Like Fractions
• 2/8 + 3/8 = (2 + 3) / 8 = 5/8

Example 2: Subtracting Like Fractions
• 7/10 – 4/10 = (7 – 4) / 10 = 3/10

Example 3: Real-World Context
• You eat 2/6 of a pie and your friend eats 1/6 → Together you ate 3/6 (simplified to 1/2)

🔢 Understanding Adding/Subtracting Like Fractions
1️⃣ Same Denominator Rule – The denominator stays the same because the parts are the same size
2️⃣ Numerators Change – Add or subtract the numerators only
3️⃣ Simplify if Needed – Reduce fractions when possible for the simplest form
4️⃣ Check Real-World Sense – Fractions should not have a numerator bigger than the denominator unless you rewrite as a mixed number

📘 Key Vocabulary and Definitions

• Like Fractions – Fractions with the same denominator
• Numerator – The number of parts you have
• Denominator – The total number of equal parts in the whole
• Simplify – To write a fraction in its smallest form
