Course 3, Lesson 30, Repeating Decimals

Author: Hector Soto
Description:

1. Use appropriate tools strategically. 2. Know that numbers that are not rational are called irrational. Understand informally that every number has a decimal expansion; for rational numbers show that the decimal expansion repeats eventually, and convert a decimal expansion which repeats eventually into a rational number. 3. Know and apply the properties of integer exponents to generate equivalent numerical expressions. 4. Use numbers expressed in the form of a single digit times an integer power of 10 to estimate very large or very small quantities, and to express how many times as much one is than the other.
