CCT CH-1 RATIONAL NUMBERS CLASS 8 MATHEMATICAL UNIT 1: FORMATION OF RATIONAL NUMBERS MrPandya told students to choose numbers and form two groups X and Y. The following numbers were chosen by the students. GROUP X: 0, − 3, 2 GROUP Y: − 6, 4, 3 He instructed students to form rational numbers of form where ‘a’ is to be chosen from group Y and ‘b’ is to be chosen from box X. Question 1.1: Although there are 6 numbers but the students form only 3 rational numbers. Why? Question 1.2: List the rational numbers formed by students. Question 1.3: How many positive rational numbers are there? (i) 1 (ii) 2 (iii) 3 (iv) 4 Question 1.4: How many negative rational numbers are there? (i) 1 (ii) 2 (iii) 3 (iv) 4 Question 1.5: How many integers are there? (i) 1 (ii) 2 (iii) 3 (iv) 4 Question 1.6:If ‘a’ is chosen from group X and ‘b’ is chosen from group Y then find the number of rational numbers formed. Question 1.7:In question 1.1 and 1.5 the numbers were chosen from same groups but still number of rational numbers formed is different. Why?​

Answer 1

Answer:

rational number y x same groups
