MULTIPLICATIVE IDENTITY • Multiplicative identity means that if we will multiply any number by a number the answer will always be same. Probability is used in our day-to-day life where we predict the chances of occurrence of various events like – today it “might rain”, we “may do this”, “without fail”, “this will surely happen” and others. Common examples of rational numbers are: 6; it can be written as 6/1 where 6 and 1 are integers; 0. This includes both rational numbers (like 7, -3, 0. Rational numbers include integers, which are whole numbers and their opposites, as well as fractions. In Lesson 7, students extend this understanding to compare rational numbers and interpret their order as it relates to real-world situations. Definition of Rational and Irrational Numbers. , are rational numbers. 1 Real Number System Card Activity.
