Do you remember KFC or LCC (it has different names) basically you leave 4/5, change the division sign to multiplication, and then change 1/3 to 3/1. Now you can multiply straight across and get 12/5. You still have to multiply this by 5/8 so multiply straight across again and you get 1.5 as your answer (it can also be written as 3/2 or 1 and 1/2).
