What is (22 1/6 + 5 7/12) i do not know the answer

Adam drew two same size rectangles and divided them into the same number of equal parts. he shaded 1/3 of one rectangle and 1/4 of the other rectangle. what is the least number of parts into which both rectangles could be divided into?

Before simplifying, how many terms are there in the expression 2x - 5y + 3 + x?
