7/15 + 5/6 = ?

The common denominator between them is thirty. So you would do 30/6 to get 5 then multiply 5 by 5 and get 25/30, then you would do 30/15 to get 2 then multiply 2 by 7 and get 14/30. Then simply add 14 and 25 together to get 39/30 and since 30 goes into 39 once that is 1 and 9/30 or 1 and 3/10.
