For anyone that has Math Destroyer 2015, for test 2 problem 35, the answer I chose was E. 28/91 but the solution said the answer is A. 4/13. Aren't these the same numbers? Both options should be correct, right?

Thanks.

They are the same. probably a typo. how did you get 28/91????

when i did the problem this is how i proceeded: (4/14)x(7/13)x2 after reducing you get 4/13.

Ohhh I see what you did. You didn't completely reduce it.

Technically A is the better answer since it's in a reduced form.
