Question

Katie is baking cookies. She starts of by having 5 2/3 cups of flour in her pantry after baking she now has only 3 1/2 cups of flour. What was the overall change?

Answer 1

5 2/3 - 3 1/2

make the fractions have the same common denominator:

2/3 = 4/6

1/2 = 3/6

5 4/6 - 3 3/6 = 2 1/6

change was 2 1/6 cups
