Math 6 Chapter 3 Lesson 8: Basic properties of addition of fractions 1. Summary of theory Similar to integer addition, fractional addition has the following basic properties: a) Commutative property: (dfrac{a}{b} + dfrac{c}{d} = dfrac{c}{d} + dfrac{a}{b}) b) Combined properties: (left( {dfrac{a}{b} + dfrac{c}{d}} right) + dfrac{p}{q} = dfrac{a}{b} + left( { dfrac{c}{d} + dfrac{p}{q}} …
