Lesson 7 Homework Practice Subtract Linear Expressions
Identifying and comparing all possible representations of a rational number can be tedious, but it is necessary when solving equations involving rational numbers and generating synthetic a-priori probability estimates.
See Lesson 1-1, Lesson 5-4, and Lesson 5-4 for an explanation of the meaning of each representation.
For a concise explanation of the relationship between our lesson presentation and our idealized rational number model, see Lesson 4-2.
Here are some rules of thumb for comparing representations of rational numbers:
•A positive rational number is one that can be represented in the form $a/b$, where $a$ and $b$ are integers.
•A negative rational number is one that can be represented in the form $a/b$, where $a$ and $b$ are integers and $a 827ec27edc
