A recipe requires 1 1/2 cups of milk for every 2/3 of a cup of flour. How many cups of milk are needed for each cup of flour?

To find out how many cups of milk are needed for each cup of flour, we can set up a proportion using the given ratio:

1 1/2 cups of milk = 1.5 cups
2/3 cup of flour = 0.67 cups

1.5 cups of milk / 0.67 cups of flour

Now, we can find out how many cups of milk are needed for each cup of flour by dividing 1.5 by 0.67:

1.5 / 0.67 = 2.23

Therefore, approximately 2.23 cups of milk are needed for each cup of flour.
