To divide rational numbers, you turn the division problem into a multiplication problem by flipping the second rational number. Then you go ahead and multiply the tops and bottoms together to get your answer. If you can simplify your problem before multiplication, you can go ahead and do so to make your problem easier.
youll get 2and 3/4 then divide by 2 and you get 1.0375=2 and 3/80
hope this helps!
