At the zoo, the yellow birds are fed 1/3 of a bag of seed each day. the blue birds get fed 1/4 as much as the yellow birds. how much of a bag of seed do the blue birds eat each day?

First, let us look at what we know. We know that the yellow birds are fed 1/3 of the bag of seeds each day.
We also know that the bluebirds get fed 1/4 as much as the yellow birds.
The question is asking us to solve how much the bluebirds eat each day. 
Well, we can simply figure that out from the information given.

Solution:
The bluebirds get 1/4 as much so they get 1/4 of the food. 1/4 of 1/3 is 0.083. That is 8/100 which simplifies down to 2/25. 

Therefore, the bluebirds are fed 2/25 of the bag of seeds each day.
