Step-by-step explanation:

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
