Answer:
The answer is A, B, and D
Step-by-step explanation:
This is really easy, all you have to do is to choose the answers that are less than 1.
Why? because anything less than 1 multiplied by a number gives you a smaller number.
Since C and E are bigger than 1 then they will give you a bigger number than 2/3.
But A, B, and D are less than 1.
So, the answer is A, B, and D
