Answer: 3 1/6 cups
Explanation:
The question is asking to find the sum of both types of flour. 1 1/2 cups of the first flour was used and 1 2/3 cups of the second was used. In order to combine these fractions, they must first have a common denominator. the fractions can be made into 1 3/6 and 1 4/6 in order to do this. Next, add the fractions to get 2 7/6 cups of flour. Finally, simplify the previous fraction to get the final answer of 3 1/6 cups.
