Answer 1

`Least\ common\ denominator:\\\\(7)/(9)\ \ \ (5)/(12)\ \ we\ need\ to\ find\ number\ which\ can\ be\ divided\ by\ 12\ and\ 9\\\\(7\cdot4)/(9\cdot4)\ \ \ (5\cdot3)/(12\cdot3)\\\\(28)/(36)\ \ \ (15)/(36)\\\\Answer\ A.`

Answer 2

the common denominator number is (i mean at least) 36.
so when we multiply 7/9 with 4/4 . NOW we have 28/36.
for the other multiply 5/12 with 3/3 now we have 15/36.
the answer is A . hope it helps :) :)
