What is the faction of red marbles in the bag?

muscrat123 · Answer

# of red / total number of marbles
what do you get ?

muscrat123 · Answer

10 of which are blue, 8 are red, 20 are green, and 12 are purple

Checking: 10 + 8 + 20 + 12 = 50 -- Good
Theoretical Ratios: Blue 10/50 = 20%, Red 8/50 = 16%, Green 20/50 = 40%, Purple 12/50 = 24%

Checking: 20 + 16 + 40 + 24 = 100 -- Good!
