Karnataka Board Class 8 Maths Chapter 7 Rational Numbers Ex 7.2<\/h2>\n

Question 1.
\nWrite down ten rational numbers which are equivalent to \\(\\frac { 5 }{ 7 }\\) and the denominator not exceeding 80.
\nAnswer:
\nMultiply both numerator and denominator by 2, 3, 4………
\n\\(\\frac{10}{14}, \\frac{15}{21}, \\frac{20}{28}, \\frac{35}{35}, \\frac{30}{42}, \\frac{35}{49}, \\frac{40}{56}, \\frac{45}{63}, \\frac{50}{70}, \\frac{55}{77}\\)<\/p>\n

Question 2.
\nWrite down 15 rational numbers which are equivalent to \\(\\frac { 11 }{ 5 }\\) and the numerator not exceeding 180.
\nAnswer:
\n\\(\\begin{array}{l}{\\frac{22}{10}, \\frac{33}{15}, \\frac{44}{20}, \\frac{55}{25}, \\frac{66}{30}, \\frac{77}{35}, \\frac{88}{40}, \\frac{99}{45}} \\\\ {\\frac{110}{50}, \\frac{121}{55}, \\frac{132}{60}, \\frac{143}{65}, \\frac{154}{70}, \\frac{165}{75}, \\frac{176}{80}}\\end{array}\\)<\/p>\n

Question 3.
\nWrite down 10 positive rational numbers such that the sum of the numerator and the denominator of each is 11. Write them in decreasing order.
\nAnswer:
\n\"KSEEB<\/p>\n

Question 4.
\nWrite down ten positive rational numbers such that numerator – denominator for each of them is -2. Write to them in increasing order.
\nAnswer:
\nNumerator – denominator = – 2
\ntherefore the denominator is greater than the numerator by 2.
\n\\(\\frac{1}{3}, \\frac{2}{4}, \\frac{3}{5}, \\frac{4}{6}, \\frac{5}{7}, \\frac{6}{9}, \\frac{7}{9}, \\frac{8}{10}, \\frac{9}{11}, \\frac{10}{12}\\)<\/p>\n

Question 5.
\nIs \\(\\frac { 3 }{ -2 }\\) a rational number? If so, how do you write it in the form conforming to the definition of a rational number (that is, the denominator as positive integer)?
\nAnswer:
\n\\(\\frac{3}{-2}\\) is a rational number because the denominator is negative.
\nIt can be written as \\(\\frac{3}{-2}\\)\u00a0since \\(\\frac{3}{-2}\\)\u00a0is same as \\(\\frac{3}{-2}\\)<\/p>\n

Question 6.
\nEarlier you have studied decimals 0.9, 0.8, can you’ write these as rational numbers?
\nAnswer:
\n\\(0.9=\\frac{9}{10} \\text { and } 0.8=\\frac{8}{10}=\\frac{4}{5}\\)<\/p>\n","protected":false},"excerpt":{"rendered":"
