A (6/9) and E (4/6)

Step-by-step explanation: So how to simplify a fraction, you find a number that both the numerator and denominator are divisible by. So for example if you have 6/9; You would divide both 6 and 9 by 3 and you would get 2/3. With E you would divide both 4 and 6 by 2 to get 2 and 3 aka 2/3.
