A recipe calls for 3/8 cups of brown sugar for every 2/3 cups of white sugar. How many cups of brown sugar are used per cup of white sugar?

9/16 Cup of Brown Sugar

Step-by-step explanation:

Convert the 3/8 Cups of Brown Sugar to 6/16 to make division easier.

So for every 2/3 Cup of White Sugar you use 6/16 Cup of Brown Sugar.

So 1/3 a Cup of White Sugar would use 3/16 a Cup of Brown Sugar.

So 3/3 or 1 Cup of White Sugar would use 9/16 a Cup of Brown Sugar
