Answer: the total cups of flour that the three ladies used is 10 5/12 cups
Step-by-step explanation:
Gayle used 3 1/4 cups of flour.
Converting 3 1/4 cups of flour to improper fraction, it becomes 13/4 cups of flour.
Irma used 2 2/3 cups of flour. Converting 2 2/3 cups of flour to improper fraction, it becomes 8/3 cups of flour.
Wynell used 4 1/2 cups of flour. Converting 4 1/2 cups of flour to improper fraction, it becomes 9/2 cups of flour.
Therefore, the total number of cups of flour that Gayle, Wynell and Irma used would be
13/4 + 8/3 + 9/2 = (39 + 32 + 54)/12
= 125/12 = 10 5/12 cups of flour.
