NCERT Solutions for Class 9 Maths<\/a> Chapter 1 Number Systems Ex 1.1 Questions and Answers are prepared by our highly skilled subject experts.<\/p>\nNCERT Solutions for Class 9 Maths Chapter 1 Number Systems Exercise 1.1<\/h2>\n Question 1. \nIs zero a rational number? Can you write it in the form \\(\\frac{p}{q}\\), where p and q are integers and q \u2260 0? \nSolution: \nYes, zero is a rational number. Because, \\(\\frac{0}{i}\\) is also equal to zero. Where is integer. Zero is also represented by \\(\\frac{0}{1}\\), which is in the form of \\(\\frac{p}{q}\\), where p and q both are integers and q \u2260 0.<\/p>\n

Question 2. \nFind six rational numbers between 3 and 4. \nSolution: \nTo find six rational number between 3 and 4, we take 3 and 4 as a rational number with denominator 6 + 1 = 7, i.e. \n3 = \\(\\frac{21}{7}\\) and 4 = \\(\\frac{28}{7}\\) \nThen required six rational number between 3 and 4 are \n\\(\\frac{22}{7}, \\frac{23}{7}, \\frac{24}{7}, \\frac{25}{7}, \\frac{26}{7} \\text { and } \\frac{27}{7}\\)<\/p>\n

Question 3. \nFind five rational numbers between \\(\\frac{3}{5}\\) and \\(\\frac{4}{5}\\). \nSolution: \nTo find five rational numbers between \\(\\frac{3}{5}\\) and \\(\\frac{4}{5}\\), we take \\(\\frac{3}{5}\\) and \\(\\frac{4}{5}\\) as a rational number with denominator 30. \ni.e. \\(\\frac{3}{5}=\\frac{3}{5} \\times \\frac{6}{6}=\\frac{18}{30}\\) and \\(\\frac{4}{5}=\\frac{4}{5} \\times \\frac{6}{6}=\\frac{24}{30}\\) \nThen, required six rational numbers between \\(\\frac{3}{5}\\) and \\(\\frac{4}{5}\\) are \n\\(\\frac{19}{30}, \\frac{20}{30}, \\frac{21}{30}, \\frac{22}{30} \\text { and } \\frac{23}{30}\\)<\/p>\n

Question 4. \nState whether the following statements are true or false? Give a reason for your answer. \n(i) Every natural number is a whole number. \n(ii) Every integer is a whole number. \n(iii) Every rational number is a whole number. \nSolution: \n(i) True, because numbers 1, 2, 3, 4, 5, ………. is a natural number and whole number is 0, 1, 2, 3, 4, 5, ……… \n(ii) False, because -1 is an integer but it is not a whole number. \n(iii) False, because \\(\\frac{1}{2}\\) is a rational number but it is not a whole number.<\/p>\n","protected":false},"excerpt":{"rendered":"
