2 1/2 because 50-20 leaves you with 30 so you have one. Than 30-20 leaves you with 10. Now you have two. There isn't another 20 but 10 is half of twenty so that gives you a half so it is 2 1/2
no you have to reduce it to 25/10 you can divide 50 and 20 both by 2 and that comes out as 25/10
hope this helps have a nice day
