In total, there are 40 marbles. 25 of those marbles are green. What I did was divide the number of green marbles by fourth, the total number of marbles. (25/40) You should come up with 0.625. Then you convert the decimal into a fraction. 5/8 is equivalent to 0.625. Thus, 5/8 of the marbles are green.
Hope this helps :)
