Answer:

D, 0.19

Step-by-step explanation:

So first you add up all the candies

you’ll get 79 pieces of candy

So 4 pieces of green candy

So we can just subtract 4 from 79 you’ll get 75 pieces

It still works becuase we know that 4 pieces gone are green so the other candies still have the same amount

Now there are 14 red pieces

So 14/75

Now simplify that and you’ll Get

0.18666666

Now round that, 0.19
