24 marbles , 16 green and 6 red what is the ratio of blue to total marbles

To find the ratio of blue marbles to the total number of marbles, we first need to determine the number of blue marbles. However, the number of blue marbles was not provided in the question. Therefore, we cannot directly determine the ratio of blue marbles to the total.

If you have additional information or if there's a mistake, please provide more details so I can help you further.

assuming that blue is the only other color, then

(24 - (16+6)) : 24 = 2:24 = 1:12
