Greta is trying to determine the portion of green candies in various bags of green and yellow candies. Using the information below, determine the portion of green candies in each bag.  

1. Bag A: Two thirds of the candies are yellow. What portion of the candies is green?

   Hint (a):

   Remember that the whole bag is a portion of $1$. What portion would go with the two thirds to complete one whole?

   Answer (a):

   $\frac{1}{3}$

2. Bag B: $29\%$ of the candies are yellow. What portion of the candies is green?

   Hint (b):

   Remember that $100\%$ represents the whole bag.

   Answer (b):

   $71\%$

3. Bag C: $4$ out of every $9$ candies are yellow. What portion of the candies is green?

   Hint (c):

   This problem is similar to both part (a) and part (b). Refer to those if you need help.

   More Help (c):

   If there are $9$ candies, and $4$ of them are yellow, how many does that leave? The remainder are all green candies.
