As the other person said 6:10 (6/10 | 6 to 10) however you wanna say it. Easy way to answer, the other variables don’t matter if you are into finding the ration of blue marbles to clear marbles. The variables for each are 6 and 10. They are asking blue first so obviously 6 would be listed for not 10:6. Thats really all, none of the other number matter because it’s only a ratio between two.
