First we know that a dozen is 12
so She makes 12×15 cookoes which is
180 cookies
so lets put it in an equation.
36 cookies = 1 cup butter
180 cookies = X
The criss cross method
36 X = 180 cup of butter (notice here that the cookie cancelled out)
dividing each side by 36 we get
5 cups of butter

<em>Comment on the method</em>
Often it works well to add the integer parts and fractional parts separately, then make adjustments in the final result.
You can convert all the numbers to improper fractions, then back:
= 8/3 + 11/3 = 19/3 = 6 1/3
Doing this requires you to do 3 conversions between mixed numbers and improper fractions, whereas the method shown above only does 1 conversion (at the end).
