Answer 1

All you have to do is add all marbles up and there is 12 marbles all together and 4 blue marbles that would be 4/12 reduced would be 1/3

Answer 2

Hey! So I know you know the answer but I felt you should know how to work it... First add all the marbles together (4+3+5=12). Then put the color you want over the total amount (in this case it would be 4: 4/12). Then simplify: 4/12=1/3 :) I hope this helps
