Find the sum:  (8/9) + (7/12)

Answer»

(8/9) + (7/12)

For addition of two unlike fractions, first change them to the like fractions.

LCM of 9, 12 = 36

Now, let us change each of the given fraction into an equivalent fraction having 36 as the denominator.

[(8/9) × (4/4)] = (32/36)

[(7/12) × (3/3)] = (21/36)

Now, add the like fractions,

= (32/36) + (21/36)

= (32+21)/36

= (53/36)

= [1(17/36)]
