1. Do Now: Real World Application 1.) You work 10 hours and earn $85. What is your earning rate? 2.) You travel 10 miles at an average speed of 45mph. How many hours does the trip take? 3.) You drive 3 hours at 65 mph. How far did you drive?

2. Algebra II 1.1: Apply Properties of Real Numbers Summer Packets: Must be turned in Monday. Quiz 1.1-1.4: next week Thursday

3. Vocabulary Real numbers consist of rational and irrational numbers. A rational number is any number that can be written as a fraction. An irrational number cannot be written as a fraction.

4. Vocabulary Terminating decimals and repeating decimals are rational. Decimals that have no pattern and do not end are irrational. Two subsets of rational numbers are whole numbers (0, 1, 2, 3, 4…) and integers (…-3, -2, -1, 0, 1, 2, 3…).
