Math 6 Chapter 3 Lesson 6: Compare fractions 1. Summary of theory Tóm 1.1. Compare two fractions with the same denominator Of any two fractions with the same positive denominator, the fraction with the larger numerator is larger. For example: Compare the following pairs of fractions a) \(\dfrac{-3}{4} ;\dfrac{-7}{4}\) b) \(\dfrac{5}{-8} … [Read more...] about Math 6 Chapter 3 Lesson 6: Compare fractions

## Math 6 Chapter 3 Lesson 4: Simplify fractions

Math 6 Chapter 3 Lesson 4: Simplify fractions 1. Summary of theory Tóm 1.1. How to shorten fractions Rule: To reduce a fraction, we divide both the numerator and denominator of the fraction by a common divisor (other than 1 and (-1)) of them. For example: Simplify fractions \(\dfrac{14}{6}\) We have UC(14, 6)=2 so we have: … [Read more...] about Math 6 Chapter 3 Lesson 4: Simplify fractions

## Math 6 Chapter 3 Lesson 3: Basic properties of fractions

Math 6 Chapter 3 Lesson 3: Basic properties of fractions 1. Summary of theory Tóm - If we multiply both the numerator and denominator of a fraction by the same non-zero integer, we get a fraction equal to the given fraction. \(\dfrac{a}{b}=\dfrac{am}{bm}, m \in Z, m\neq0\) For example: \(\dfrac{2}{5} = \dfrac{{2.2}}{{5.2}} = … [Read more...] about Math 6 Chapter 3 Lesson 3: Basic properties of fractions

## Math 6 Chapter 3 Lesson 2: Equal fractions

Math 6 Chapter 3 Lesson 2: Equal fractions 1. Summary of theory Tóm Two fractions \(\dfrac{a}{b}\) and \(\dfrac{c}{d}\) are said to be equal if the cross product \(ad=bc\). Example 1: \(\dfrac{-5}{3}=\dfrac{10}{-6}\) because \((-5).(-6)=3.10\) \((=30)\); \(\dfrac{-4}{9} \neq \dfrac{-5}{11}\) because \(-4.11\neq 9.(-5)\) 2.
