8. Write in a form so that the numerator is equal to: 42 (ii) 7 (iii) 42 (iv) -70 9. Select those rational numbers which can be written an motionalni (1) -​

Answer 1

Answer:

(i) Given (-14/42) To get numerator -2 we have to divide both numerator and denominator by 7 Then we get, (-14/42) ÷ (7/7) = (-2/6) Therefore (-14/42) as a rational number with numerator -2 is (-2/6) (ii) Given (-14/42) To get numerator 7 we have to divide both numerator and denominator by -2 Then we get, (-14/42) ÷ (-2/-2) = (7/-21) Therefore (-14/42) as a rational number with numerator -14 is (-14/21) (iii) Given (-14/42) To get numerator 42 we have to multiply both numerator and denominator by -3 Then we get, (-14/42) × (-3/-3) = (42/-126) Therefore (-14/42) as a rational number with numerator 42 is (42/-126) (iv) Given (-14/42) To get numerator -70 we have to multiply both numerator and denominator by 5 Then we get, (-14/42) × (5/5) = (-70/210) Therefore (-14/42) as a rational numbRead more on Sarthaks.com - https://www.sarthaks.com/681089/write-14-42-in-a-form-so-that-the-numerator-is-equal-to-i-2-ii-7-iii-42-iv-70
