Mastering Fraction Comparison with LCD

Learn to compare and order fractions, mixed numbers, and improper fractions by renaming them to the Lowest Common Denominator (LCD). Understand the concept that fractions with the same denominator are easily compared, while fractions with differing denominators can be renamed by applying the LCD strategy.

  1. Objective: You will learn how to compare and order fractions, including mixed numbers and improper fractions, by renaming them to the Lowest Common Denominator (LCD).

  2. You know that… • fractions with the same denominator can be readily compared • two fractions with differing denominators can be renamed by applying the LCD

  3. Compare and order fractions, including improper fractions and mixed numbers, by using the LCD. • Strategy • Get all numbers to the same form • Get all numbers to have common denominators

  4. Solve a problem involving the comparison and ordering of mixed numbers. Problem: Compare 4/5 and 5/16. • Strategy • Rename the fractions to the LCD

  5. Conclusion: You learned how to compare and order fractions, including mixed numbers and improper fractions, by renaming them to the Lowest Common Denominator (LCD). • To simplify fractions to lowest terms, apply the GCF • To rename or compare fractions, apply the LCM
