\nIs the number \\(\\frac{2}{-3}\\) rational? Think about it.
\nAnswer:
\nYes, \\(\\frac{2}{-3}\\) is a rational number,
\n\u2235 2 and -3 are integers and -3 \u2260 0.<\/p>\n
Question 2.
\nList ten rational numbers.
\nAnswer:
\nFollowing are ten rational numbers:
\n\\(\\frac{1}{3}, \\frac{-2}{3}, \\frac{4}{5}, \\frac{1}{-6}, \\frac{-3}{-4}, 5.8,2 \\frac{4}{5}\\), 0.93, 18 and 11.07
\nNote: 1. \u20180\u2019 can be written as \\(\\frac{0}{2}\\) or \\(\\frac{0}{15}\\) etc.
\nHence, it is a rational number.
\n2. A natural number can be written as
\n5 = \\(\\frac{5}{1}\\) or 108 = \\(\\frac{108}{1}\\) Hence, it is also a rational number.<\/p>\n

\nAnswer:
\n(i) \\(\\frac{-2}{3}\\) is a negative rational number.
\n(ii) \\(\\frac{5}{7}\\) is a positive rational number.
\n(iii) \\(\\frac{3}{-5}\\) is a negative rational number.
\n(iv) 0 is neither a positive nor a negative rational number.
\n(v) \\(\\frac{6}{11}\\) is a positive rational number.
\n(vi) \\(\\frac{-2}{-9}\\) is a positive rational number.
\n\u2234 (i) \\(\\frac{-2}{3}\\) and (ii) \\(\\frac{3}{-5}\\) are negative rational numbers.<\/p>\n
NCERT In-text Question Page No. 178<\/span><\/p>\nQuestion 1.
\nFind the standard form of:
\n(i) \\(\\frac{-18}{45}\\)
\n(ii) \\(\\frac{-12}{18}\\)
\nAnswer:
\n(i) Since HCF of 18 and 45 is 9.
\n\u2234 \\(\\frac{-18}{45}=\\frac{(-18) \\div 9}{45 \\div 9}=\\frac{-2}{5}\\)
\nThus, the standard form of \\(\\frac{-18}{45}\\) is \\(\\frac{-2}{3}\\)<\/p>\n
(ii) Since HCF of 12 and 18 is 6.
\n\u2234 \\(\\frac{-12}{18}=\\frac{(-12) \\div 6}{18 \\div 6}=\\frac{-2}{3}\\)
\nThus, the standard form of \\(\\frac{-12}{18}\\) is \\(\\frac{-2}{3}\\)<\/p>\n
