Set up a proportion.

5/2 = 1/x

Cross multiply:

2 = 5x

Divide 5 to both sides:

x = 2/5

So 2/5 cups of water are needed for 1 cup of flour.
The answer is D, 2/5 cup.
So you are trying to find how many cups of water for 1 cup of flower. The given hint is 2 cups of water for every 5 cups of flour.S
So you divide 2 into 5 which makes 2.5. 2.5 is the same as 2/5 therefore D is the answer.  :)
