Christopher bought 4 bags of powdered sugar. He got a total of 7 1/2 cups of sugar. How many cups of sugar were in each bag? Simplify your answer and write it as a proper fraction or as a whole or mixed number.
1 7/8 or 15/8 because you flip the 4/1 to 1/4 and multiply that by 15/2 and you get 15/8 or 1 7/8
