Question

3/5 * X * - 4/7 - 2/14 - 4/7 * 6/5 (Find using properties)​

Answer 1

Answer:

(i) -2/3 x 3/5 + 5/2 - 3/5 x 1/6 = -2/3 x 3/5 - 3/5 x 1/6 + 5/2 ( Using commutativity of rational number) = (-3/5) x (2/3 + 1/6) + 5/2 (Distributivity) = (-3/5) x (2x2 + 1/6) + 5/2 = 0-3/5) x (5/6) + 5/2 = (-3/6) + 5/2 = (-3+5 x 3/6) = (-3 + 15/6) = 12/6 = 2 (ii) 2/5 x (-3/7) - 1/6x3/2 + 1/14 x 2/5 = 2/5 x (1/14x2/5 - 1/6x32 (By commutativity) = 2/5 x (-3/7 + 1/14) - 1/4 = 2/5 x (-3x2 + 1/14) - 1/14 2/5 x 9-5/14_ - 1/4 = -1/7 - 1/4 = -4 -7/28 = -11/28Read more on Sarthaks.com - https://www.sarthaks.com/105267/using-appropriate-properties-find-i-2-3-x-3-5-5-2-3-5-x-1-6
