(a) How many of the bag's blue marbles were chosen?
I thought 10 because I did 5/8*16=10

(b)How many of the bag's green marbles were not chosen?
Not enough information

(c) How many of the bag's marbles were chosen?
17.5
5/8*12=15/2=7.5+10=17.5

I agree with everything except  Part c.
If it is asking how many marbles were chosen you would just add the green and blue and it would equal 22 because $$\frac{ 5 }{ 8 }\times 16=10~then ~10+12=22$$
