Answer:
Step-by-step explanation:
In the question is given to verify the property x × (y + z) = x × y + x × z The arrangement of the given rational number is as per the rule of distributive property of multiplication over addition. Then, (-2/3) × ((-4/6) + (-7/9)) = ((-2/3) × (-4/6)) + ((-2/3) × (-7/9)) LHS = (-2/3) × ((-4/6) + (-7/9)) = (-2/3) × ((-12 – 14)/18) = – (2/3) × (-26/18) = – (1/3) × (-26/9) = 26/27 RHS = ((-2/3) × (-4/6)) + ((-2/3) × (-7/9)) = ((-1/3) × (-4/3)) + ((-2/3) × (-7/9)) = (4/9) + (14/27) = (12 + 14)/27 = 26/27 By comparing LHS and RHS LHS = RHS ∴ 26/27 = 26/27 Hence x × (y + z) = x × y + x × zRead more on Sarthaks.com - https://www.sarthaks.com/845784/verify-the-property-x-y-z-x-y-x-z-of-rational-numbers-by-taking-x-2-3-y-4-6-z-7-9
