Lets say 4 times 4/8 all you do is put 4 over one like so, 4/1 then multily across 4x4 is 16 then 8x1 is 8 so you get 16/8 then you can simplify. :)
+9 It depends on the fraction, If the fraction has 1 as the numerator you would divide by the denominator. An example is 6x1/3 you would basically divide 6 by 3, so that would equal 2. But if it was a fraction that doesn't have 1 as the numerator say you were trying to find 12x3/4. You would find what is 3/4 of 12 and that would equal 9. Sorry if I'm not the best at explaining things! ^.^ I hoped this help something :P.
