➗ Decompose Fractions into Unit Fractions
📖 What the Section Is About
In this topic, students learn how to break any fraction into smaller unit fractions. A unit fraction has a numerator of ¹ and represents one equal part of a whole. Using visual models, students can see how larger fractions are made up of these smaller parts.
🎯 Learning Objectives
✅ Recognize a unit fraction as ¹/ₙ
✅ Break fractions into sums of unit fractions
✅ Use models to visualize decomposition
✅ Write fractions as a sum of unit fractions in different ways
✅ Apply decomposition in addition and subtraction problems
🧪 Examples
-
³/₄ = ¹/₄ + ¹/₄ + ¹/₄
-
