Explanation:
This is a ratio question. They give you the ratio of 2:3. So for every 2 of something you will have 3 of the other. In the case of 4 eggs (having 3 cups of flour for EVERY 2 eggs) will mean 6 cups of flour. If you ask yourself "how many sets of 2 eggs do I have per item?" that will tell you what to add to the number of eggs to get the cups of flour.
