Rational numbers in the number line
1) Rational numbers are numbers that can be written as a quotient of two integers, such as a/b where b does not equal 0. They include integers as well as fractions and terminating or repeating decimals. 2) The document provides examples of rational numbers and asks students to determine if examples are rational numbers and to plot them on a number line. 3) Students are given practice locating rational numbers on a number line, such as -5/3, and asked to plot multiple rational numbers on a single number line.
