Answer:

B is correct

Explanation:

Product is the answer to a multiplication problem:

-2 (
(1)/(6))(
(-1)/(4))(9)

Can be written:


(-2)/(1))(
(1)/(6))(
(-1)/(4))(
(9)/(1)) Multiple all of top numbers together and all of the bottom numbers together. Since we have 2 negative signs, the answer will be positive. When you are multiplying a group of numbers, count the negative signs. If you get an even number, your answer will be positive. If you get an odd number, your answer will be negative.


(18)/(24) Divide the top and bottom by 6 to simplify and you get


(3\\)/(4)
