What is the difference from these 2 problems? They seem to be the same thing but they are different. For the one I got 4/51... That is because I did 20/255 and went to fraction mode which gave me 4/51. But for the other I got 2/5. Which was not counting all the numbers but only the root beers, which was 30/75 going to fraction which gave me 2/5.. I am just wondering, when I have to count the entire given and when I am going to just count a certain section.
