Hello everyone. I've been browsing through the forums a bit, and it looks like this is probably going to be one of the easier questions on here. I haven't taken a math class in over 10 yrs and can't remember anything .. could someone help me with this problem? I've searched all over online, but can't find an example exactly like this one. I know the answer is supposed to be 16/9, but how do you get there?
(I should also add that there are parenthesis around )
