🍕 Subtract Mixed Numbers with Like Denominators

📖 What the Section Is About

In this lesson, students learn how to subtract mixed numbers that share the same denominator. We subtract the whole numbers first, then the fractions. Sometimes regrouping is needed when the top fraction is smaller than the one being subtracted.

🎯 Learning Objectives

✅ Understand how to subtract mixed numbers with like denominators
✅ Subtract whole numbers and fractions separately
✅ Regroup mixed numbers when needed
✅ Simplify answers to lowest terms
✅ Apply subtraction of mixed numbers to real-life problems

🧪 Examples

  • 5 ⁶/₈ − 2 ³/₈ = 3 ³/₈

  • 7 ⁴/₆ − 3 ²/₆ = 4 ²/₆ = 4 ¹/₃

  • 6 ²/₁₀ − 4 ⁵/₁₀ = 1 ⁷/₁₀

📘 Key Vocabulary and Definitions

  • Mixed Number: A whole number plus a fraction (e.g., 3 ²/₅)

  • Regrouping: Borrowing 1 from the whole number and turning it into a fraction to subtract more easily

  • Simplify: Reduce fractions to their simplest form
