Positive Rational Numbers

Unit 1 focuses on Positive Rational Numbers, which consists of Natural Numbers (Positive Numbers), Decimals, and Fractions. The Standard Algorithm for Division is applied to converting Improper Fractions to Mixed Numbers, and the Standard Algorithm for Multiplication is applied to converting Mixed Numbers to Improper Fractions. In addition, Multiplication and Division are utilized to write Prime Factorizations. These Prime Factorizations are used to determine the GCF (Greatest Common Factor), LCM (Least Common Multiple), Simplify Fractions, and Cross-Cancel when Multiplying and Dividing Fractions.
