Answer:
black= 2/15 green= 4/15
Step-by-step explanation:
so first we find out what this is out of so we add them all together which comes to 15. so there are 15 pencils. Since they're 4 green out of all 15 pencils it will be a 4/15 its same for black with 2/15. (sorry if it's not good, I hope this helped)
