Simplify: (2/3) + (5/6) – (1/9)

Answer»

(2/3) + (5/6) – (1/9)

LCM of 3, 6, 9 = 18

Now, let us change each of the given fraction into an equivalent fraction having 18 as the denominator.

= (2/3) × (6/6) = (12/18)

= (5/6) × (3/3) = (15/18)

= (1/9) × (2/2) = (2/18)

Then,

= (12/18) + (15/18) – (2/18)

= (12+ 15 – 2)/ 18

= (27-2)/ 18

= (25/18)

= [1(7/18)]
