Make it the same denominator so you can add them (18.) Multiply 5/9 by 2 and multiply 4/6 by 3. 10/18 + 12/18 = 22/18. Since there is not 22/18 listed, you can use this fraction as a proportion. The only proportion that can be evident is answer A, as when you multiply 22/18 by 3, you get 66/54. Your answer is A.
