NCERT Solutions for Class 8 Maths Chapter 1 Rational Numbers Exercise 1.2<\/h2>\n

Question 1.
\nRepresent these numbers on the number line:
\n(i) \\(\\frac{7}{4}\\)
\n(ii) \\(\\frac{-5}{6}\\)
\nSolution:
\n(i) \\(\\frac{7}{4}\\)
\nWe make 7 markings at distance of \\(\\frac{1}{4}\\) each on the right of 0 and starting from 0, the seventh marking represents \\(\\frac{7}{4}\\).
\n\"NCERT<\/p>\n

(ii) \\(\\frac{-5}{6}\\)
\nWe make 5 markings at distance of \\(\\frac{1}{6}\\) each on the left of \u20180\u2019 and starting from \u20180\u2019, the fifth marking represents \\(\\frac{-5}{6}\\)
\n\"NCERT<\/p>\n

Question 2.
\nRepresent \\(\\frac{-2}{11}, \\frac{-5}{11}, \\frac{-9}{11}\\) on a number line.
\nSolution:
\nWe make 9 markings at distance of \\(\\frac{1}{11}\\) each on the left of ‘0’ and starting from ‘0’, the second marking represents \\(\\frac{-2}{11}\\); the fifth marking represents \\(\\frac{-5}{11}\\) and the ninth marking represents \\(\\frac{-9}{11}\\).
\nThe point A represents \\(\\frac{-2}{11}\\), the point B represents \\(\\frac{-5}{11}\\) and the point C represents \\(\\frac{-9}{11}\\).
\n\"NCERT<\/p>\n

Question 3.
\nWrite five rational numbers which are smaller than 2.
\nSolution:
\nThere can be infinite rational numbers smaller than 2.
\nFive rational numbers are 0, -1, \\(\\frac{1}{2}\\), \\(\\frac{-1}{2}\\), 1<\/p>\n

\"NCERT<\/p>\n

Question 4.
\nFind ten rational numbers between \\(\\frac{-2}{5}\\) and \\(\\frac{1}{2}\\)
\nSolution:
\nConvert \\(\\frac{-2}{5}\\) and \\(\\frac{1}{2}\\) with the same denominators.
\n\\(\\frac{1}{2}=\\frac{1 \\times 5}{2 \\times 5}=\\frac{5}{10}\\)
\n\\(\\frac{-2}{5}=\\frac{2 \\times 2}{5 \\times 2}=\\frac{-4}{10}\\)
\nTo get ten rational numbers, multiply both numerator and denominator by 2
\n\\(\\frac{5}{10}=\\frac{5 \\times 2}{10 \\times 2}=\\frac{10}{20}\\)
\n\\(\\frac{-4}{10}=\\frac{-4 \\times 2}{10 \\times 2}=\\frac{-8}{20}\\)
\nThe rational numbers between \\(\\frac{10}{20}\\) and \\(\\frac{-8}{20}\\) are
\n\\(\\frac{9}{20}, \\frac{8}{20}, \\frac{7}{20}, \\frac{6}{20}, \\frac{5}{20}, \\frac{4}{20}, \\frac{3}{20}, \\ldots \\frac{-6}{20}, \\frac{-7}{20}\\)
\nWe can take any 10 of them.<\/p>\n

Question 5.
\nFind five rational numbers between
\n(i) \\(\\frac{2}{3}\\) and \\(\\frac{4}{5}\\)
\n(ii) \\(\\frac{-3}{2}\\) and \\(\\frac{5}{3}\\)
\n(iii) \\(\\frac{1}{4}\\) and \\(\\frac{1}{2}\\)
\nSolution:
\nConvert \\(\\frac{2}{3}\\) and \\(\\frac{4}{5}\\) with the same denominators
\n\\(\\frac{2}{3}=\\frac{2 \\times 5}{3 \\times 5}=\\frac{10}{15}\\)
\n\\(\\frac{4}{5}=\\frac{4 \\times 3}{5 \\times 3}=\\frac{12}{15}\\)
\nThe difference between the numerators should be more than 5
\n\\(\\frac{10}{15}=\\frac{10 \\times 4}{15 \\times 4}=\\frac{40}{60}\\)
\n\\(\\frac{12}{15}=\\frac{12 \\times 4}{15 \\times 4}=\\frac{48}{60}\\)
\nFive rational numbers between \\(\\frac{40}{60}\\) and \\(\\frac{48}{60}\\) are
\n\\(\\frac{41}{60}, \\frac{42}{60}, \\frac{43}{60}, \\frac{44}{60}, \\frac{45}{60}\\)<\/p>\n

(ii) Convert \\(\\frac{-3}{2}\\) and \\(\\frac{5}{3}\\) with the same denominators.
\n\\(\\frac{-3}{2}=\\frac{-3 \\times 3}{2 \\times 3}=\\frac{-9}{6}\\)
\n\\(\\frac{5}{3}=\\frac{5 \\times 2}{3 \\times 2}=\\frac{10}{6}\\)
\nFive rational numbers between \\(\\frac{-9}{6}\\) and \\(\\frac{10}{6}\\) are \\(\\frac{9}{6}, \\frac{8}{6}, \\frac{7}{6}, 0, \\frac{-7}{6}\\)<\/p>\n

(iii) Convert \\(\\frac{1}{4}\\) and \\(\\frac{1}{2}\\) with the same denominators
\n\\(\\frac{1}{4}=\\frac{1}{4}\\)
\n\\(\\frac{1}{2}=\\frac{1 \\times 2}{2 \\times 2}=\\frac{2}{4}\\)
\nThe difference between the numerators should be more than 5
\n\\(\\frac{1}{4}=\\frac{1 \\times 8}{4 \\times 8}=\\frac{8}{32}\\)
\n\\(\\frac{2}{4}=\\frac{2 \\times 8}{4 \\times 8}=\\frac{16}{32}\\)
\nFive rational numbers between \\(\\frac{8}{32}\\) and \\(\\frac{16}{32}\\) are \\(\\frac{9}{32}, \\frac{10}{32}, \\frac{11}{32}, \\frac{12}{32}, \\frac{13}{32}\\)<\/p>\n

\"NCERT<\/p>\n

Question 6.
\nWrite five rational numbers greater than -2.
\nSolution:
\nThere are infinite rational numbers greater than -2.
\nThe numbers are \\(\\frac{-3}{2},-1, \\frac{-1}{2}, 0, \\frac{1}{2}\\)<\/p>\n

Question 7.
\nFind ten rational numbers between \\(\\frac{3}{5}\\) and \\(\\frac{3}{4}\\).
\nSolution:
\nConvert \\(\\frac{3}{5}\\) and \\(\\frac{3}{4}\\) with the same denominators
\n\\(\\frac{3}{5}=\\frac{3 \\times 4}{5 \\times 4}=\\frac{12}{20}\\)
\n\\(\\frac{3}{4}=\\frac{3 \\times 5}{4 \\times 5}=\\frac{15}{20}\\)
\nThe difference between the numerator should be more than 10.
\n\\(\\frac{12}{20}=\\frac{12 \\times 8}{20 \\times 8}=\\frac{96}{160}\\)
\n\\(\\frac{15}{20}=\\frac{15 \\times 8}{20 \\times 8}=\\frac{120}{160}\\)
\nThus, ten rational numbers between
