Represent means __________. CFU Activate Prior Knowledge • A unit fraction represents one part of a whole. • The numeratorof a unit fraction is always 1. • The denominatorrepresents the number of total • equal parts. Represent the unit fraction on the number line. 1. 2. Students, you already know how to represent unit fractions on a number line. Now, we will use unit fractions to represent fractions on a number line. Make Connection 1 show (synonym) Vocabulary
