Answer 1

Okay so your question seperated into 4 question however in all the question you need to add the total sum up.
8+2+7+3=20
Now we can start
Blue:
There is blue 2 marbles.
So your fraction will end up being 2/20 or 1/10
Red:
There is  8 red marbles.
So your fraction will be 8/20 or 2/5
Yellow:
There is 7 yellow marable
so your fraction will be 720.
Green:
3 green marble
so it will be 3/20
